Disabled IPv6 may be breaking Anyconnect for me

The IPv6 addressing attempt get permission denied eventhough earlier in the workflow, IPv6 addresses are to be treated as fake while Ipv4 is real.

Is there a way to disable/enable IPv6 support during runtime? Or some other solution for this? The improvements on the latest builds are very helpful so any help on this is greatly appreciated.

I'm currently back to the October 10th build.
