VPN keeps disconnecting — how to fix

A VPN can disconnect when the underlying network changes, the device sleeps, or the selected connection method does not work reliably on that network. Test one change at a time so you can identify what helps.

1. Check the connection without the VPN

1. 1Disconnect HorizonVPN
2. 2Open two or three normal websites or use the built-in Speed test
3. 3If the connection also fails without the VPN, reconnect Wi-Fi or mobile data before testing HorizonVPN again

2. Return the protocol to Auto

1. 1Open Settings and find Connection
2. 2Select Protocol and choose Auto
3. 3Reconnect to a nearby location

3. Try Connection compatibility

1. 1In the Connection section, open Connection compatibility
2. 2Leave it on Automatic first
3. 3If your current network needs a regional compatibility preference, choose the matching option and reconnect

• On mobile, allow HorizonVPN to run without aggressive battery restrictions
• Avoid switching repeatedly between Wi-Fi and mobile data during the test
• Try another nearby location if only one location disconnects
• Use Report an issue shortly after the next drop if the problem continues
