WKD on http2 server

Hi,

we had trouble with our wkd on archlinux32.org.

gpg only said "gpg: error retrieving 'buildmaster at archlinux32.org' via 
WKD: General error".

No (failed or successul) accesses were logged server side during a tried 
`gpg --locate-key ...`.

We switched off http2 (removed "http2" parameter from nginx' "listen" 
directive) and key location via wkd workes.

I now wonder, whether:

1. This is known.
2. This is documented.
3. It is intended to change this.

("this" = "key retrieval via wkd does not work with (some?) http2 
servers")

Also, it would be nice to give a somewhat more detailed error message, 
like "cannot connect to https://$domain".

regards,
Erich
