A question about WKD

[Stefan Claas]

Hi all,

hope you all had a nice Christmas!

I have set up WKD on my VPS, in order to learn more about it and get now
the following error:

gpg --encrypt -r sac at 300baud.de OpenSSL.txt
gpg: error retrieving 'sac at 300baud.de' via WKD: Not trusted
gpg: sac at 300baud.de: skipped: Not trusted
gpg: OpenSSL.txt: encryption failed: Not trusted

I assume that dirmngr is downloading my cert and thinks it
is not trusted. However, my site uses a popular Comodo cert.

Any ideas what is going on here and how to fix this?

Regards
Stefan
