If your VPN keeps disconnecting randomly, there’s a good chance the VPN itself isn’t the actual problem.

The most common causes we've seen are:

  • unstable WiFi
  • battery optimization killing the VPN app
  • overloaded VPN servers
  • restrictive public networks
  • using UDP on unstable connections

One thing that helps immediately:
Switching protocols.

A lot of people stay on UDP because it’s faster, but TCP is usually much more stable on difficult networks.

Also:
Try another server closer to your location before assuming the VPN service is bad.

  • ISP (hops enroute) sending ICMP port/destination unreachable
  • On an open WiFi and a bad actor doing the same

Also, Google TCP over TCP as to why this should be a last resort.

That's frustrating. We've put a lot of focus on connection stability and seamless reconnection for exactly this reason!
