A. 1. Check your internet connection: Ensure you have a stable Wi-Fi or mobile data connection. Try switching between Wi-Fi and mobile data to see if the issue persists. 2. Restart the app: Close the app completely and reopen it. This can help re-establish a connection to the server.

B. 3. Change DNS settings: Go to your device's Wi-Fi settings, long-press your connected network, select 'Modify network', and change the DNS to 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS). This can sometimes resolve connectivity issues.
