Mobile VPN disconnects after sleep or in the background

3 min read·Updated September 16, 2026

Check operating-system battery, background, and Always-on behavior when a mobile connection does not stay active.

  1. 1Update HorizonVPN and the mobile operating system
  2. 2Set Protocol to Auto and reconnect on a stable network
  3. 3On Android, allow HorizonVPN to run without aggressive battery optimization or background restriction
  4. 4On Android, use Always-on VPN and optionally Block connections without VPN when continuous protection is required
  5. 5Check whether switching between Wi-Fi and mobile data is causing the disconnect
  6. 6Report the issue soon after the next drop if it continues

Battery and background-setting names vary by phone manufacturer and operating-system version. Use the system page for the installed HorizonVPN app rather than a third-party cleaner or task-killer.
