Hi there! I see you're encountering a "Server not found, please check if ID is correct. (1065537)" error on the BonChat app. Let’s work together to get this sorted out.

To start, can you share if this error pops up right after you enter your ID, or does it happen during some other part of using the app? Also, have you already tried checking your internet connection or restarting the app?

Meanwhile, here’s a step-by-step approach to try fixing this issue on your Mac running OS X 10.15.7:

1. Verify Your ID: Double-check that the ID you’re entering is correct—sometimes a small typo can cause this error.

2. Check Internet Connection: Make sure your Mac is connected to a stable Internet source. You can try opening a website to confirm.

3. Restart BonChat App: Close the app completely (Command + Q), then reopen it and try logging in again.

4. Update the App: See if there’s an update available for BonChat. On Mac, open the App Store, go to Updates, and install any available updates.

5. Restart Your Mac: Sometimes, a simple reboot resolves networking glitches.

6. Firewall/Antivirus Settings: Ensure your firewall or antivirus software is not blocking BonChat. You can check this in System Preferences > Security & Privacy > Firewall.

7. Reinstall the App: If none of the above works, try uninstalling BonChat and installing it again to clear corrupted files.

If after these steps the problem persists, I can guide you through more advanced diagnostics or share a detailed video guide that walks through solutions for BonChat login issues and crashes1.

Could you please let me know which steps you've tried already and if anything changed after you attempted them? That way we can focus on the next best step together.

Are you satisfied with the solution I provided so far?
