Until a certain point, everything was fine with the VPN connection. But 10 days ago the connection possibility disappeared and the message is displayed:

"The VPN connection "Name_VPN_Connection" disconected because VPN service stopped"

In this case, the connection to another VPN server is fine. This connection recreated, but beztolku.

Alarming in the logs:

 NetworkManager[2759]: CHAP authentication failed

What could be the reason?
