This event happens when the user is connects to the VPN from multiple computers or locations. The VPN will restart every minute.
To avoid this, please ensure that you are logged in from only one computer or location. Having multiple connections to the VPN can cause such issues as the environment can only support one active connection at a time.
In order to break the connection, you should use CTRL-C. Closing the terminal or just the laptop/vm can still leave the connection active.
