Will the Client update itself?

Maybe it does. I just went to update mine and see that it is already at 2.2 and looks to have installed on 6/29. I don't recall that I did that.

A bigger issue for me is that this client disconnects me every 1:25. The old SSLVPN client didn't have this issue using exactly the same firewall and login. I opened a ticket, but no response yet.

Hey Joe, can you help me with the Firewall version you're trying to connect to. Also the config file extension would help.

Joe, I have a customer having somewhat similar issues. 8 hours on the dot after they connect for the first time, they get disconnected. It will show they were logged off in the firewall, but I have the AD/SSO setting set for 10 hours and VPN timeouts to unlimited. Also, makes me wonder if this is a MFA timeout as well.

This only happens with the new vpn client. The old client is continuing to work just fine. We have 12 hour key lifetime on the ssl vpn. I have no idea where this 1:25 interval is coming from, but looking at the client log was very consistent.

Our firewall is running 19.0.0 GA-Build317

should be related to the rekey timeout on server's side! with v19 you are able to set rekey time interval vi GUI.
The issue here is 2FA if enabled for Remote Access VPNs via SC, since the Client tries to reconnect after rekey-timeout, the connection can't be hold because 2FA proposals are out of date and must be reentered by the user with current OTP ;-)

We already had the key lifetime set to 12 hours (43200 seconds). The old SSL VPN client doesn't have this problem, just the new Sophos Connect Client. openvpn client also is fine.
