Are you not reading what I am saying to you?? Once again, your explanation is INVALID because that would mean that gnupg would be BROKEN, because it would be a NON-COMPLIANT http client according to the RFC I quoted.
I explained why the keyserver access requires access to the DNS. If that is not possible the keyserver code will not work. If you don't allow DNS to work you either have to use Tor (which we use to also tunnel DNS requests) or get your keys from elsewhere. Also note that the keyserver network is current several broken and under DoS and thus it is unlikely that it can be operated in the future.

HTTP/1.1 spec, RFC 7230, Section 5.4, paragraph 2:
Please be so kind and point me to the specs stating that you should put the IP address into Host:
It's up to GPG to send the Host header that shows the user's intent.
So in short you want:
- Allow to specify a keyserver by IP without any DNS lookups.
- When connecting via IP use the IP address for Host:.

Also might I add, this used to work perfectly fine in gnupg14. It seems that somewhere along the line a regression was introduced that is causing this erroneous non-compliant behavior in the HTTP client.
Why? Your explanation is invalid because it implicates dirmngr's HTTP client as not comforming to the spec laid out by the RFC. I've quite clearly explained--and backed up with the spec itself--that when a proxy variable is configured, a client should not be doing DNS lookup of the destination hostname. Is there something about that you are not understanding?
Please show an example regarding something else than a failed access to a pool of keyservers. I explained why it can't work for pools for you.

Yes you can, and no you do not. Don't believe me? Then read the spec. At no point does the spec say that there is "nothing that can be done" when a hostname cannot be resolved when connecting through a proxy. In fact, it states precisely the opposite, describing the exact procedure a client should take when making a request through a proxy. See section 5.3, paragraph 3:
No we can't we need to know the IP addresses to handle the pools. I have given a workaround for you in my previous comment. You can also use install Tor which we can use for DNS resolving.

So if your DNS resolver does not tell us the IP addresses, we can't do anything about it.

If you specify a pool of keyservers dirmngr selects a keyserver on its won from the pool. This is so that it can use its own heuristics to detect whether a keyserver is dead and then retry another one. Now the default is a pool and your specified keyserver.ubuntu.com is also a pool (of two servers). So if your DNS resolver does not tell us the IP addresses, we can't do anything about it.

It seems that this part of the code was not finished. Unfortunately upstream of the dns code is unresponsive and thus we started to maintain the code base by ourselves. There is still an open question whether we should do that to the full extend, in which case we would integrate the code closer into the GnuPG framework with its own logging subsystems.

A workaround for this until the HTTP client is fixed is to just use curl instead:
I am running into the same exact issue. It seems that dirmng is incorrectly attempting to resolve the addresses for the keyservers despite having been given an HTTP proxy to connect through.

Applied to 2.2 branch.

And 2.2 branch.
Fixed in master.

I'll fix for the non-FQDN case.
I think that I identified the issue. This is the libdns (dirmngr/dns.c) problem when hostname is not FQDN.
If you change it to FQDN, you can see that it tries to search adding the domain name.
Fixed in master.
It is indirectly reported at the upstream: https://github.com/wahern/dns/issues/19

An option to ignore SRV records would also be good for debugging. Thus I raised the priority and truned this into a feature request.
@Beiri22: It was my fault to to tell you to use scdaemon.conf. The correct conf file is of course dirmngr.conf. However, with @BenM comments I don't think that it is a bug at all. I am thus closing this; please feel free to re-open if we were wrong
