# Port Forwarding or SSH connections stop working when switching apps on Android

This can happen when battery optimization is enabled for Termius. In that mode, Android may restrict background activity and stop SSH sessions or port forwarding after you switch apps.

To keep SSH sessions and port forwarding active in the background, disable battery optimization for Termius. Open your Android app settings, find **Termius**, turn off **battery optimization**, and allow **unrestricted** background usage.
