Hi there! I understand that Plotagon Story on your Mac running OS X 10.15.7 shows a "no internet connection" message even though your internet is working, and when you hit retry, it keeps saying the same thing. Let's try to sort this out together.

First, can you tell me a bit more?
- Are you connected via Wi-Fi or Ethernet?
- Have you tried restarting your Mac since this started happening?
- Also, are other internet-dependent apps working fine for you?

Assuming your internet is stable and other apps work, here’s a step-by-step approach to fix Plotagon’s connection issue:

1. Restart Plotagon Story app:
- Quit the app completely (Cmd + Q), then relaunch it. Sometimes the app needs a fresh start.

2. Restart your Mac and network hardware:
- Restart your Mac.
- Also, power cycle your modem/router by turning it off for 30 seconds and then on.

3. Check firewall and network settings:
- Go to System Preferences > Security & Privacy > Firewall and ensure Plotagon is allowed to access the internet.
- If you have any VPN or proxy configured, try disabling it temporarily as it may interfere with app connectivity.

4. Clear app cache or reinstall Plotagon Story:
- Sometimes cached data causes connection issues. If you can access the app’s data folder (usually under ~/Library/Application Support/), try to locate Plotagon’s cache and clear it.
- If that’s tricky, an alternate method is to uninstall the app and reinstall it fresh from the official source.

5. Check for app updates:
- Make sure Plotagon Story is updated to the latest version compatible with OS X 10.15.7.

6. Network Diagnostics:
- Open Safari or another browser and check if websites load normally.
- Run Network Diagnostics (from Network preferences, click Assist me > Diagnostics) to identify any underlying network issues.

If after these steps the problem continues, it could be due to server-side issues or account-related problems. In that case, I can help you escalate or verify your account status with Plotagon support.

Would you like help walking through any of these steps? Also, if you already tried some, please let me know so I don’t repeat them.

Looking forward to your reply!
