> Yes, but look at the error message.  It matches what you saw from GnuPG.  It looks like libcurl tries the IPv4, fails, then the IPv6, and fails again.  It only displays an error message for the IPv6 as that was the last thing tried.  The keyserver handler uses libcurl as well, and is doing the same thing.

You're correct. tcpdump has confirmed that the initial attempt is done
over IPv4. Still, the error message returned from gpg is misleading...
