So I gave up and did a fresh install. Right after the fresh install I had ipv6 connectivity verified with sites like https://test-ipv6.com/. Once I finished the web wizard my ipv6 went away. I eliminated all variables by making zero chnges in the web wizerd and ipv6 still went away after completing the web wizard.
The wizard doesn't support IPv6. Could be side effect since the rewrite, but in any case it makes more sense to finish the IPv6 support:
