But with:
ServerTransportListenAddr obfs4 <ipv4-addr>:<port> ServerTransportListenAddr obfs4 [<ipv6-addr>]:<port>
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

I've ran into this problem too. On IRC I was suggested to run a vanilla bridge (without obfuscation) and that's what I've done. In torrc, I have two ORPort lines, one with only the port for IPv4 and one with address:port for IPv6. Dont forget to enclose the IPv6 address in square brackets.
