Hi there! I understand how frustrating it can be when you're unable to connect to the server. Let's troubleshoot this together.

First, can you confirm if you're using a stable internet connection? Sometimes connection issues can arise if you're on cellular data with a weak signal or if your Wi-Fi is intermittent. It may help to try switching between Wi-Fi and mobile data to see if that resolves the issue.

If that doesn't work, here are some steps we can try:

1. Restart Your Device: Sometimes a simple restart can resolve connectivity issues.

2. Clear App Cache:
- Go to Settings on your Android device.
- Tap on Apps or Applications.
- Locate OpenTable, then tap on it.
- Tap on Storage and then select Clear Cache.

3. Check for App Updates:
- Go to the Google Play Store.
- Search for "OpenTable" and see if there's an update available. If so, update the app.

4. Reinstall the App: If the above steps don’t work, uninstalling and then reinstalling the OpenTable app can sometimes resolve issues.

5. Check for Server Outages: You can check if OpenTable's servers are facing issues by visiting Is It Down Right Now.

After trying these steps, let me know if you're still having trouble connecting. We'll figure this out together!
