Forticlient 7.4.1.1697 on Ubuntu 22.04.5 failing to create SSL tunnel

It's basicly what the title says. We use forticlient to connect to the company's VPN. I was told that the request reaches successfully the server but when it tries to create the ssl tunnel it fails. I already tried to reinstall, changing the wifi connection used.

Here I have extracted some info from the sslvpn.log file that I think relates to the problem.
Could you help me please?

Can you check if you have nmcli on the host?

Just run "nmcli -v".

I am having the same problem, but it only happens with WIFI, not ethernet!

EDIT:
Reverting to forticlient 7.4.0-GA solved the issue for me.

$ nmcli -v
nmcli tool, version 1.36.6

I also set network manager's debug level:

As @Jamie_Pate_FTNT I had to downgrade to 7.4.0 and mark the forticlient on hold by now (at least until 7.4.2)

I'm having the same issue on Ubuntu 24.04.5 LTS.
Establishing the SSL VPN over Wifi kills the connection.
If I connect the VPN while connected via Ethernet it works.

I had to downgrade back to 7.4.0. It works as expected.

Here's some lines from the Journal. It seems EDR was the one killing the connection

Strange that EDR blocks VPN of FCT 7.4.1 while it allows 7.4.0.

Unfortunately we can't see any reason in the logs.

I guess it is possible to add an exception in EDR to allow the denied VPN connection.

I think the errors look different.

As workaround try use "fortisslvpn" which is a NM plugin. I've been using it for a long time and it has always worked perfectly.

Forticlient 7.4.2 is out. Did anyone try it yet?
Supposedly the solved issues are the VPN connections
