I see some IPv6 patches in backport, while getting twisted.internet.error.CannotListenError: Couldn't listen on dead:beef:f:d::cc:8443: [Errno 43] Protocol not supported. Is this expected to work in 4.2? If yes, does the TLS/cert code handle dual stack addresses? Axel --- PGP-Key:29E99DD6 ☀ +49 151 2300 9283 ☀ computing @ chaos claudius
