    Description

      As per our discussion on slack, there should be mostly no situations where IPv6-only works but IPv6 does not. But for some reason, I am able to repro this consistently on my vagrant box. When I init the cluster with IPv6 option, it goes thru fine. But when I try it with IPv6-only option, it does not work. Spinner comes up and lands in the same setup page again. Once I land in this state, I cannot init the cluster with any other options. Have to reinstall the server to proceed.

      Please note that this is on my vagrant box. So something might be up with the settings. Here is the ifconfig on that box:
