Sorry, the output of gpgconf referred to a changed configuration. This
is what happens for me with GnuPG 2.3.4:

value for `keyserver` in gpg.conf → keyserver used with `--refresh-key`
hkp://keys.gnupg.net → hkp://pgp.surf.nl
hkp://keys.openpgp.org → hkp://keys.openpgp.org
[empty] → hkps://keyserver.ubuntu.com
