OpenConnect v9.01 - output appears after "ESP session established with server"

[Schütz Dominik]

Hi,

I have installed the new OpenConnect version 9.01 on Ubuntu 22.04 (packages from https://launchpad.net/ubuntu/+source/openconnect/9.01-1/+build/23596572), after a while I get an output after "ESP session established with server", what could be the reason?

dominik at host2:~$ sudo openconnect --script=/root/vpnc-script --protocol=pulse https://vpn-gateway/linux
Connected to xxx.xxx.xxx.xxx:443

By the way, it makes no difference in the output whether I use the "vpnc" from GitHub or the one from Ubuntu in the "vpnc-scripts" package.
