After upgrading to 7.2.7.0905: vpn_connection:2072 Config DNS failed

I'm using the forticlient with Ubuntu 24.04.1 LTS. 

After running an apt upgrade the forticlient was also upgraded from version 7.2.5.0854 to 7.2.7.0905. Now I'm no longer able to connect to my VPN. 

I get the following error messages in the log file sslvpn.log: 

20241217 17:58:10.901 TZ=+0100 [sslvpn:EROR] nmtools:255 Command to set ipv4.ignore-auto-routes returned with status 256. 20241217 17:58:10.901 TZ=+0100 [sslvpn:EROR] nmtools:1060 Failed to modify connection docker0 property ipv4.ignore-auto-routes 20241217 17:58:10.901 TZ=+0100 [sslvpn:EROR] dns:1007 Failed to finish Network Manager configuration 20241217 17:58:10.901 TZ=+0100 [sslvpn:EROR] vpn_connection:2072 Config DNS failed

I have already removed some docker interfaces, which occurred before in the log as error messages, but I cannot remove the docker0 interface, only to get the client running. 

I have also upgraded to the Version 7.4, but I get the same error messages. I tried to downgrade to version 7.2.5.0854, but I can no longer find in the repository or anywhere else the old package.
