What do you mean by "hang" here? It appears that OpenConnect is
working perfectly normally.

You did not pass it the -b/--background option, so the openconnect
process is running in the foreground. The openconnect process needs
to keep running, because it's entirely responsible for passing traffic
between the kernel device, tun0, and the VPN gateway; it can run in
either the foreground or the background.

If you can open another terminal window and connect to hosts inside
the VPN network, then it's working fine... you are just a single
command-line option away from preventing it from "hanging" :-P
