Hi there! I see you're encountering error code 0-v10.4 (2025.37.0)-A2-gg9999-w with the Gotham Sports app. Let me help you get that sorted out.

To start, can you tell me a bit more about when this error shows up? For example, does it happen when you try to log in, start a stream, or at another point? Also, have you tried any fixes so far like reinstalling the app or checking your internet connection?

Meanwhile, here’s a common approach that has helped others with similar Gotham Sports error codes:

1. Restart your device and router – power cycling often clears connection glitches.
2. Clear the cache of the Gotham Sports app, if possible, or uninstall and reinstall the app to fix corrupted data.
3. Ensure your Windows 10 system and browser (WebKit-based) are up to date.
4. Verify your account doesn’t have multiple entitlements linked, as that can sometimes cause these errors (like multiple subscriptions or logins).
5. Try switching your network connection; for instance, if you’re on Ethernet, try Wi-Fi or vice versa.

If you’ve already tried these, let me know which ones and if the issue persists after those steps. We can then look at advanced settings or account verification to clear this up.

Are you ready to give these a try?
