Do you get this error straight away, or after a timeout?

Any chance of you running tcpdump or wireshark to capture what traffic
Emacs is sending?

You may have a not-quite-working IPv6 setup, which is causing Emacs to
try to connect via IPv6 and failing rather than falling back to IPv4.
Could you let us know which version of Emacs this is? Also that
network trace would be *really* useful.
Thanks
