Hi there! I see you're having trouble connecting to the Tanghulu Master app server on your Android 10 device using WebKit browser. Let me help you get this sorted out.

To start, could you tell me if the app shows any specific error message when it says it can’t connect? Also, are you on Wi-Fi or mobile data? Sometimes the connection type and network settings can affect app connectivity.

In the meantime, here are some steps you can try to troubleshoot this issue:

1. Check Internet Connection
Make sure your device is properly connected to the internet. Try opening other websites or apps that require the internet to confirm.

2. Restart the Device and App
Close the Tanghulu Master app fully, restart your phone, and then open the app again.

3. Clear App Cache and Data
Since you’re on Android 10, go to Settings > Apps > Tanghulu Master > Storage, then tap on ‘Clear Cache’ first. If the problem persists, try ‘Clear Data’ (note: clearing data may require you to log in again).

4. Check App Update
Make sure Tanghulu Master app is updated to the latest version as updates often address server connectivity issues.

5. Verify Server Status
Sometimes the app servers might be down temporarily. If you can, check any official Tanghulu Master social media or support channels to see if there are announcements about server issues.

If after these steps you still get the connection error, there are a couple more things to try:

6. Network Settings Reset
Go to Settings > System > Reset > Reset Wi-Fi, mobile & Bluetooth. This will reset network settings but won’t delete your data.

7. Try Connecting on Another Network
If possible, connect to a different Wi-Fi hotspot or switch between Wi-Fi and mobile data to see if the problem is network-specific.

8. Reinstall the App
Uninstall Tanghulu Master, then download and install the latest version again from your app store.

If none of the above solves the issue, it could be related to a known server bug or account problem. Some reports mention bugs affecting server connections2. In that case, I can help you draft an email to [email protected] for further assistance.

Please try these and let me know what happens or if you see any specific error messages. I’m here to help! Are you satisfied with this initial solution?
