Hello, I'm on a network where there is no IPv6 connectivity. When I try to fire up openconnect, it tries to connect via IPv6 and there does not seem to be an option to force IPv4. I now removed the DNS entry and waiting for it to time out, but I wonder if there is a trick, otherwise I would probably would make a patch ready.
