I've been successfully connected to a VPN by Ubuntu for a long time (since 2019). Yesterday, I started to get an error "Something went wrong. Please try again.Code: 40".
I contacted the network admin from my company and she informed me of an error with simultaneous login. But, I tried to login, in the same machine, via Windows 11, with the same certificate (.p12), and I successfully connected to VPN. I've cleaned all my history and cookies in Google Chrome, and I tried Firefox too, and I got the same error. My Ubuntu version is 22.04 LTS and, as I mentioned above, I've been successfully connected to a VPN with Ubuntu, including with this version until yesterday.
