Any idea what's wrong?

Hello,

I'm not surprised to be honest. I have no access to an ipv6-only machine to test, so could you help me with this? Could you try updating https://github.com/libc/em-redis/blob/0525c425ec7279bff1842969331da937123d2d9f/lib/em-redis/redis_protocol.rb#L318 to localhost?

Thank you.

Aah, okay. That's interesting, heh. Let me try that out and get back to you! :)
