A. 1. Restart the VPN app and try connecting again. 2. Check your internet connection; switch between Wi-Fi and mobile data to see if the issue persists. 3. Change the VPN protocol in the app settings (e.g., from OpenVPN to IKEv2) to see if that stabilizes the connection.
B. 4. Clear the app cache by going to Settings > Apps > VPN Bucks > Storage > Clear Cache. 5. Reinstall the app to ensure you have the latest version and all settings are reset.
