Hi! I see you’re having an issue with the GettingOut app showing an "unknown address" error when trying to video chat. Let’s work through this together.

First, just to understand better:
- Is this happening every time you try to start a video chat, or did it start after a specific event like an app update?
- Are you connected to Wi-Fi or mobile data?
- Have you recently changed your phone number or updated your account info on the app?

Meanwhile, here’s a step-by-step approach to try fixing it:

1. Restart the app and your device: Close the app completely, then turn your phone off and back on. Sometimes, a simple restart can clear temporary glitches.

2. Check for app updates: Go to the app store and ensure your GettingOut app is up to date. Updates often fix known bugs.

3. Verify your account settings: Sometimes the “unknown address” error can relate to mismatched or missing contact details. Open the app, go to your account or profile, and confirm your phone number and email are current and verified. You can do this by selecting "View My Account" and verifying details.

4. Clear app cache: On your Android 10 device with WebKit browser, go to Settings > Apps > GettingOut > Storage, then tap “Clear Cache.” This removes temporary data that might cause issues.

5. Check network connectivity: Ensure your internet connection is stable. If on Wi-Fi, try switching to mobile data or vice versa. Also, avoid VPNs or firewalls that might block app connections.

6. Reinstall the app: If none of the above works, uninstall the GettingOut app, then download and install it fresh.

If these steps don't resolve the issue, it might be related to a backend or server issue with GettingOut’s video chat system. They have been known to experience occasional problems and usually work quickly to fix them.

Would you like me to look into any recent service notices or escalate this to GettingOut support? Also, can you confirm if you have access to the app’s account details so we can check the phone number verification properly?

Looking forward to helping you get this working!
