Hi there! I understand that your NASA app is having trouble fetching resources like images and telemetry, often leading to timeouts. Let's get to the bottom of this so you can have a smoother experience.

To start, could you tell me:
- Are you connected via Wi-Fi or Ethernet?
- Is this happening all the time or mostly during certain hours?
- Have you noticed if this happens with all resources or only specific ones such as images or telemetry data?
- Have you tried any fixes so far, like restarting the app or your Mac?

Meanwhile, I’ll guide you through some basic troubleshooting steps catered to your Mac OS X 10.15.7:

1. Check Your Internet Connection
Make sure your Mac has a stable connection. You can do this by:
- Opening Safari and visiting a few websites to see how fast pages load.
- Trying a speed test (e.g., https://www.speedtest.net) to verify your bandwidth.

2. Restart the App and Mac
Sometimes, closing and reopening the app can clear temporary glitches. After that, restart your Mac to refresh the network stack.

3. Verify App Permissions and Firewall Settings
Ensure that the app has permission to access the internet:
- Go to System Preferences > Security & Privacy > Firewall.
- Check if the firewall is enabled and, if so, whether it’s blocking the app.
- Also, review System Preferences > Network to see if any proxy is interfering.

4. Check for App Updates
- Make sure the app is updated to the latest version compatible with macOS 10.15.7. Sometimes, outdated versions have compatibility issues causing timeouts.

5. Clear App Cache or Data (if applicable)
Some apps store temporary data that might become corrupted. See if the app allows clearing cache within settings or by reinstalling it.

If you are still facing issues after these steps, the problem might relate to how the app contacts NASA’s servers or how telemetry packets are formatted and fetched, which can also cause timeouts2. For advanced troubleshooting, the app might need to optimize API calls to avoid timeouts, especially when fetching heavier data like images or telemetry4.

Could you please share what your experience is with the above steps, and if you can pinpoint when these timeouts mostly occur? That way, I can assist with more tailored fixes or escalate if needed.

Are you satisfied with this initial direction?
