A. 1. Check your internet connection: Ensure you have a stable internet connection. Try switching between Wi-Fi and mobile data to see if the issue persists. 2. Adjust app settings: Go to V2Box settings and lower the timeout settings if available, or switch to a different server if the app allows it.
B. 3. Disable battery optimization: Go to 'Settings' > 'Battery' > 'Battery Optimization' and find V2Box. Set it to 'Not Optimized' to prevent the system from restricting the app's background activity.
