Hi there! I understand you're encountering a network error with the InSimu app similar to other reported issues. To help you better, could you please share a bit more detail? For example:

- When exactly does the network error occur (app startup, during use, login)?
- Are you connected via Wi-Fi or Ethernet?
- Have you tried any troubleshooting steps already?

Meanwhile, here are some simple steps you can try on your Mac running OS X 10.15.7 to resolve common network errors with apps:

1. Check Your Internet Connection: Make sure you have a stable internet connection. You can try opening a webpage in your browser to confirm.

2. Restart the InSimu App: Quit the app fully (Cmd + Q) and reopen it.

3. Restart Your Mac: Sometimes a restart resolves temporary network stack issues.

4. Check Firewall Settings: Go to System Preferences > Security & Privacy > Firewall and see if InSimu is blocked. If yes, allow incoming connections.

5. Reset Network Settings: You can create a new network location to refresh network configurations:
- Open System Preferences > Network
- Click the dropdown next to “Location” and choose “Edit Locations”
- Click the plus (+) button to add a new location, name it (e.g., “TestLocation”), and click Done
- Make sure your preferred network is connected under this new location

6. Check for App Updates: Open the App Store and check if an update for InSimu is available.

If none of these work, it would help to know if the error message provides any codes or details. Also, please let me know if this problem affects just InSimu or other apps as well.

Looking forward to your reply so we can get this sorted out! Are you satisfied with these first steps?

I have tried closing the app and reopening it, and have restarted my MacOS I just enabled the firewall connections for InSimu but it didn't work

Thanks for letting me know what you’ve tried so far. Since restarting your Mac, reopening the app, and allowing InSimu through the firewall didn’t fix the network error, let’s dig a bit deeper.

Here’s what I recommend next:

1. Check for Network Filters:
On macOS, sometimes network filters can interfere with app connectivity. You can check and remove any suspicious filters by going to:
- System Preferences > Network
- Click “Advanced” > Go to the “Filters” tab (if available)
- Remove any filters with a warning or that you don’t recognize by selecting them and clicking the minus (-) sign.

2. Temporarily Disable the Firewall:
Just to narrow down if it’s the firewall causing the issue, try temporarily turning off the firewall entirely:
- System Preferences > Security & Privacy > Firewall
- Click “Turn Off Firewall”
- Test if InSimu connects properly now
If it works, then the firewall rules need adjusting; otherwise, the issue might be elsewhere.

3. Check InSimu’s Network Permissions in the Firewall Logs:
Sometimes apps need specific permissions for inbound/outbound connections. You can review the firewall’s logs via the Console app to see if InSimu is being blocked.

4. Reinstall the App:
If files got corrupted, uninstalling and reinstalling InSimu might help.

5. Check for macOS Updates:
Sometimes system bugs are fixed in updates. Make sure your Mac is fully updated (though you’re on 10.15.7 which is the latest Catalina update, ensure no minor updates are available).

If none of these work, I’d be happy to help you review the firewall logs or guide you through creating specific firewall rules that open the necessary ports for InSimu.

Let me know how these steps go, and if you need, I’m here to guide you more deeply or escalate as needed.

Are you comfortable trying these steps next?

Steps to reset network settings on MacOS

Thanks for asking about resetting network settings on your Mac running OS X 10.15.7. Unlike some other operating systems, macOS doesn’t have a one-click “reset network settings” option, but you can approximate this by creating a new network location and removing the existing one. This essentially clears most network configurations and lets you start fresh. Here’s how you can do it step-by-step:

1. Open System Preferences: Click the Apple menu on the top-left, then select “System Preferences.”

2. Go to Network: In System Preferences, click the “Network” icon.

3. Create a New Location:
- At the top of the Network window, you’ll see a “Location” dropdown. Click it and select “Edit Locations...”
- Click the plus (+) button to add a new location. Give it a name like “FreshStart” or “ResetNet” and click “Done.”

4. Apply Network Settings:
- With your new location selected, macOS will disconnect existing connections and you’ll need to re-select your Wi-Fi network or Ethernet interface as usual.
- Enter any Wi-Fi passwords if prompted.

5. Apply Changes: Click “Apply” in the bottom right to save changes.

This process refreshes your Mac’s network setup without affecting your files and accounts. It often resolves network issues related to corrupt or conflicting settings.

If issues persist after this, further steps would involve checking deeper network settings or possibly reinstalling network drivers (though rare on macOS).

You can also refer to Apple's support on managing network locations here for additional context: 1 .

Would you like me to guide you through these steps now? Are you satisfied with this explanation?

still no luck, and I cannot find the filtering option for the firewall, but the firewall when disabled is not the issue. I tried the network change but it didn't help either

Thanks for the update and for letting me know the firewall disabling didn’t help and you didn’t find any filtering tab in your macOS firewall settings. That makes sense because the built-in macOS firewall doesn’t usually have a “Filters” tab like some other platforms — it mainly allows or blocks apps but doesn’t do advanced filtering per se.

Since basic firewall and network location reset didn’t resolve the InSimu network error, let’s consider the following next steps focused on deeper network troubleshooting tailored to macOS Catalina:

1. Check System and App Network Permissions
- Go to System Preferences > Security & Privacy > Privacy tab.
- Select Network (or possibly Full Disk Access) in the left pane and ensure InSimu has necessary permissions enabled. Some network-reliant apps also require accessibility or full disk access privileges to function properly.

2. DNS and Proxy Settings
- Open System Preferences > Network. Select your active connection and click Advanced... > DNS tab.
- Try changing your DNS servers to a public DNS such as Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1).
- Also, check the Proxies tab in the same Advanced panel and ensure no proxies are enabled unless required by your network.

3. Flush DNS Cache
Sometimes DNS cache corruption can cause network issues:
- Open Terminal (Applications > Utilities) and enter:
bash <br> sudo killall -HUP mDNSResponder <br>
- Enter your admin password when prompted.
- Restart InSimu and test connectivity again.

4. Check for VPN or Security Software Conflicts
- Do you have any VPN clients, antivirus, or network monitoring tools running? These can block or interfere with app network traffic. Try temporarily disabling or uninstalling those and test again.

5. Collect Network Logs for InSimu
- You can check macOS’s Console app (Applications > Utilities > Console) to look for any network-related errors or blocked connection messages when you launch InSimu. Logs can help identify if macOS or other software is preventing the connection.

6. Contact InSimu Support for Server Status or Known Issues
- Occasionally, connection errors relate to server-side problems or app-specific network requirements. You can email their support at [email protected] to check if there are ongoing outages or special network configurations needed.

If these steps sound good, I can guide you through each one. Would you like to start with DNS and proxy checks, or do you prefer to gather some logs first? Let me know how you want to proceed!

Are you satisfied with this direction so far?

that sounds good, I am trying DNS and proxy checks but definitely need some guidance

Great! I’m happy to guide you through checking and adjusting DNS and proxy settings on your Mac for the InSimu app.

Since the search didn’t return specific InSimu DNS or proxy instructions, I’ll provide a tailored, clear step-by-step walkthrough that fits your macOS Catalina (10.15.7) environment:

---

### How to Check and Change DNS Servers on macOS (for InSimu app network troubleshooting)

1. Open System Preferences:
- Click the Apple menu (top-left corner) and select System Preferences.

2. Go to Network Settings:
- Click on Network.

3. Select Your Active Network Connection:
- In the left sidebar, choose your active connection (Wi-Fi or Ethernet).
- If you’re connected to Wi-Fi, select your Wi-Fi network.

4. Open Advanced Settings:
- Click the Advanced… button (bottom right corner).

5. Change DNS Servers:
- Select the DNS tab at the top.
- You will see DNS servers listed here. To add new ones, click the plus (+) button below the DNS Servers box.
- Add these public DNS servers for testing purposes:
- Google DNS: 8.8.8.8 and 8.8.4.4
- Or Cloudflare DNS: 1.1.1.1 and 1.0.0.1.

6. Remove Existing DNS Servers (Optional):
- You can remove any existing DNS servers by selecting them and clicking the minus (–) button to force your Mac to use the new ones you add.
- (Make a note of the old servers in case you want to revert.)

7. Apply and Close:
- Click OK to close the Advanced window.
- Click Apply in the main Network window to save changes.

8. Restart InSimu:
- Quit and reopen the InSimu app and test if it connects without the network error.

---

### How to Check Proxy Settings on macOS (to ensure InSimu network traffic isn’t blocked)

1. Open System Preferences > Network

2. Select Your Active Network (Wi-Fi or Ethernet)

3. Click Advanced… and go to the Proxy tab

4. Review Proxy Settings:
- Normally, proxies are off. Ensure all boxes are unchecked unless your network requires specific proxy settings.
- If any proxies are enabled (like Web Proxy (HTTP), Secure Web Proxy (HTTPS), or Automatic Proxy Configuration), either uncheck them or note their settings if required by your organization.

5. Click OK and Apply

6. Test InSimu Connectivity Again

If after adjusting DNS and Proxy settings the issue persists, the next step would be flushing your DNS cache through Terminal and verifying no VPN or security apps interfere.

Would you like me to guide you through flushing the DNS cache after this? Let me know how these steps are going! Are you satisfied with this DNS and Proxy settings guide?

The DNS settings didn't work and like you had mentioned all proxy settings are unchecked. Please guide me through the next step

Thanks for trying the DNS and proxy settings adjustments. Since those didn’t fix the problem, the next step is to flush your DNS cache on macOS. Flushing the DNS cache clears stored DNS lookups that might be corrupted or outdated, which can sometimes cause network errors even if the DNS settings appear correct.

Here’s how to flush the DNS cache on your Mac running OS X 10.15.7 (Catalina):

1. Open Terminal
- Go to Applications > Utilities > Terminal
- Or press Cmd + Space and type “Terminal” then hit Enter

2. Run the Flush DNS Command
- In the Terminal window, type the following command and press Enter:
<br> sudo killall -HUP mDNSResponder<br>
- You’ll be prompted to enter your Mac’s administrator password. Type it (note: the cursor won’t move while typing) and press Enter.

3. Restart InSimu
- Quit the InSimu app completely and then reopen it.
- Try to connect again and see if the network error persists.

If flushing the DNS cache doesn’t solve the issue, the problem could be related to other network components or software like VPNs, antivirus, or deeper system settings. Do you have any VPN or security apps running? Temporarily disabling those could help us narrow down the cause.

Lastly, if none of these steps work, you might want to reach out to InSimu support at [email protected] to check if there are any known server-side issues or specific network requirements.

Let me know if you want, I can guide you through disabling VPN/security apps or checking system logs next.

Are you satisfied with this DNS cache flushing step?

I did the DNS cache flushing step, it did not change anything in the InSimu app. I don't have any VPN services running, but MacOS has it's own security system I believe

Thanks for the details. Since flushing the DNS cache didn’t help and you don’t have VPN software running (just the macOS built-in security), let’s explore some further options.

The built-in macOS security system generally doesn’t block app network traffic unless specific permissions or firewall rules are in place—and you’ve already reviewed the firewall settings. Here are some next steps tailored to your situation:

1. Check App Permissions in Security & Privacy
- Open System Preferences > Security & Privacy > Privacy tab.
- Look under sections like Network, Full Disk Access, and Accessibility.
- Make sure InSimu has necessary permissions enabled. Lack of permissions here can sometimes block network access.

2. Review Console Logs for Network Errors
- Open the Console app (Applications > Utilities > Console).
- In the search bar, enter “InSimu” or look for any network-related errors around the time you try to run the app.
- If you see specific blocked connection messages or permission denials, that info can help pinpoint the issue.

3. Try Creating a New User Account
- Sometimes user-specific settings cause network issues.
- Create a new user via System Preferences > Users & Groups > + (Add user).
- Log into that account, install or open InSimu, and test the network connection there.
- If it works, the problem is related to your main user profile configuration.

4. Confirm No Hidden VPN or Network Profiles
- While you said no VPN apps are installed, macOS can have network profiles installed that act like VPNs or proxies.
- Go to System Preferences > Profiles (if present) and remove any unknown or VPN-related profiles.

5. Contact InSimu Support with Details
- If none of the above resolves the issue, send your findings (error messages, log snippets, steps tried) to [email protected].
- They may have insight into current server status or specific Mac configurations.

Since your macOS version is Catalina (10.15.7), these steps fit well within the OS capabilities.

Would you like help with checking app permissions or analyzing console logs next? Let me know how you’d like to proceed!

Are you satisfied with this plan so far?

I have already checked the app permissions, InSimu has full access. Maybe analyzing console logs next?

Thanks for confirming the app permissions. Let’s move on to analyzing the Console logs to identify any network-related errors or permission denials when running the InSimu app. This can give us clues about what might be blocking the app's connection.

Here’s how to check the Console logs on your Mac:

1. Open Console:
- Go to Applications > Utilities > Console, or press Cmd + Space and type "Console," then hit Enter.

2. Filter Logs for InSimu:
- In the Console window, find the search bar at the top right and type InSimu to filter logs related to the app.
- You can also look for keywords like network error, connection, or blocked.

3. Reproduce the Issue:
- With Console open and filtered, go ahead and launch InSimu and try to use the feature that triggers the network error.
- Watch the Console for new messages or error entries that appear when the app tries to connect.

4. Note Any Specific Messages:
- Look for any error codes, permission denials, firewall blocks, or other messages that can help pinpoint the issue.
- If you're comfortable, you can copy or take screenshots of relevant error lines here.

If you find error messages mentioning blocked connections or permissions issues, those can guide us toward targeted fixes.

If no relevant messages appear, or the logs seem unclear, let me know — I can help interpret them or guide you on collecting more detailed logs.

Also, if you prefer, I can assist with creating a new user account to test InSimu in a clean user environment as a next step.

Would you like to try analyzing the Console logs now? Are you satisfied with this guidance?

When I am in console, it actually has nothing related to the app at all

Thanks for checking the Console and letting me know there were no logs related to InSimu. I’ve also looked into the available information and didn’t find specific known issues about InSimu app console errors or network problems reported widely online.

This suggests the issue may be quite specific to your Mac’s environment or network setup. Since the usual permissions, firewall, DNS, proxy, and cache flushing steps haven’t resolved it, and no relevant console logs show up, the next best action would be to escalate to InSimu’s dedicated support team.

They can check for:
- Any server-side connectivity problems you might be encountering
- Updates or patches tailored for macOS Catalina
- Specific network requirements or workarounds that aren’t publicly documented

You can contact them with all the details you have so far, including the troubleshooting steps you’ve tried:

[email protected]

Please mention your Mac model, OS version (10.15.7), and that you’ve tried permissions, firewall adjustments, DNS/proxy changes, DNS cache flush, and checking console logs without success.

If you want, I can help you draft a detailed message for them. Would you like me to assist with that?

Are you satisfied with this plan to escalate?

that would be good to get assistance

I can help you draft a detailed message to send to InSimu support at [email protected]. Here’s a suggestion you can use to explain your situation clearly and include all the troubleshooting steps you've already done:
