That is likely "host not found" or "domain not found". Maybe a problem with your resolver. Please add

log-file /foo/bar/dirmngr.log
verbose
debug ipc,dns

to ~/.gnupg/dirmngr.conf and restart dirmngr ("gpgconf --kill dirmngr"). I would also suggest to remove your --keyserver and use the default which is actually what keys.gnupg.net points to.

What is the output of

gpg-connect-agent --dirmngr 'getinfo dnsinfo' /bye

and what is the content of your /etc/nsswitch.conf and /etc/resolv.conf ? Is there anything special in your /etc/hosts? Are you using any kind of non mainstream DNS resolver on your system or network?

$ gpg-connect-agent --dirmngr 'getinfo dnsinfo' /bye
OK - Libdns stub resolver

/etc/hosts is empty
/etc/nsswitch.conf is the default
/etc/resolv.conf contains the corporate DNS

$ cat /etc/resolv.conf
# Generated by resolvconf
...

Are you using any kind of non mainstream DNS resolver on your system or network?

Quite possible. This is the first time in that I have issues with pacman -> gpg though.
