Unable to connect via IPv6

Sorry in advance if this is just a configuration error on my end but I cannot figure it out.

When I try to connect to my taskd server at

task.example.com:54321

I get the error message

failed to connect to task.example.com/aaaa:bbbb:ccc:d:eee:f:gg:hh:ii:jj (port 54321) from /:: (port 98765): connect failed: ECONNREFUSED (Connection refused)

I don’t understand the address it is trying to connect to which seems to have an IPv6 address appended to it and I also don’t understand where the second port number comes from.

I seem to be having this issue as well when I use my own taskd and my hostname. As soon as I replace my hostname with the ipv4 address instead of the domain name, the app starts working correctly. Perhaps there is an issue with handling the ipv6 addresses?

\o Adding some info here because this might not actually be a bug in foreground, but instead related to a bug in taskd, in which it is not able to listen dual stack. Basically that means right now: pick an address family and stick to it or (much better) write a patch for taskd.

I’ll try to replicate but, since my mobile internet provider doesn’t support v6, I fell back to running this particular service v4-only for the time being.
