$ gpg --locate-key release@gentoo.org gpg: error retrieving 'release@gentoo.org' via WKD: Server indicated a failure gpg: error reading key: Server indicated a failure
So I've enabled the debug-level guru for dirmngr. However, it didn't produce anything useful:

Finally, via strace I've been able to figure out that DNS is timing out:
[pid 8076] connect(7, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.53")}, 16) = 0
[pid 8076] sendto(7, "\331^\1\0\0\1\0\0\0\0\0\1\v_openpgpkey\4_tcp\6ge"..., 56, 0, NULL, 0) = 56
[pid 8076] recvfrom(7, 0x7f3d1000877c, 4096, 0, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)
[pid 8076] select(8, [7], [], NULL, {tv_sec=1, tv_usec=0}) = 0 (Timeout)
[pid 8076] recvfrom(7, 0x7f3d1000877c, 4096, 0, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)

[pid 8076] select(8, [7], [], NULL, {tv_sec=1, tv_usec=0}) = 0 (Timeout)
[pid 8076] close(7) = 0It would be really nice if the error messages (or at least the detailed debug log) mentioned name resolution somewhere, so that I wouldn't waste my time trying to figure out what's wrong with the HTTP server.
This is GnuPG 2.2.17 on Gentoo.
