Who manages the server that hosts debian.koha-community.org? It looks like it’s actively refusing connections from one of my Koha servers.
Err:9 http://debian.koha-community.org/koha 20.11 InRelease
Could not connect to debian.koha-community.org:80 (67.220.127.145), connection timed out
I was able to connect just fine from a different IP address, and that server can contact many other Apt repos.
