Hi! I see you're having trouble with the "No server connection" error in Shadow Fight 4. Let’s work together to get that fixed.

Can you tell me a bit more?
- Are you connected to Wi-Fi or mobile data?
- Have you tried switching between them?
- Have you restarted your device or the game since the issue started?

Once I have that info, I can guide you more precisely. Meanwhile, here are some initial steps to try:

1. Check Internet Connection: Make sure your Android device has a stable internet connection. Try opening a website in your browser to confirm.

2. Switch Network: If you are on Wi-Fi, try switching to mobile data or vice versa. Sometimes the network might be blocking certain game servers.

3. Restart the Game and Device: Close Shadow Fight 4 completely and restart your Android device. This can clear temporary glitches.

4. Clear App Cache: Go to Settings > Apps > Shadow Fight 4 > Storage > Clear Cache. This won't delete your data but may fix corrupted temporary files.

5. Check for Updates: Make sure Shadow Fight 4 is updated to the latest version in your app store. Older versions can have connection issues.

6. Disable VPN or Proxy: If you are using a VPN or proxy, try disabling it as it might interfere with the server connection.

If after trying these you still can’t connect, it might be related to ISP restrictions or server-side issues. Then, using a VPN temporarily to check if the game connects can be helpful. If VPN works, your Internet Service Provider might be blocking the game servers, and contacting them would be the next step.

Let me know what you’ve already tried or what you observe when doing these steps, and we’ll proceed from there! Are you satisfied with this initial guidance?
