But with:

obfs4proxy is only listening on the IPv4 address!
It looks like you are encountering https://bugs.torproject.org/11211
Alas, I suggest sticking to ipv4 for now -- I think if you got ipv6 working on your obfs4, you would next run into the problem that bridgedb doesn't currently give out ipv6 obfs4 addresses.
There's a lot of work waiting for somebody who wants to make ipv6 more of a proper citizen in the Tor world. There's a mention by Sarah of a recent funding proposal which could get that restarted again: https://lists.torproject.org/pipermail/tor-project/2019-September/002479.htm...
Thanks for running a bridge! --Roger
