From this, it sounds like the HTTP server on <domain>.freedombox.rocks
is not reachable from the public Internet.  It needs to be in order for
the "http-01" validation method to work [1].

What happens if you try to visit http://<domain>.freedombox.rocks/ in a
browser, preferably from a public Wifi network or some other independent

What happens when you run

  getent ahosts <domain>.freedombox.rocks

from a Linux workstation?

Is the freedombox behind another router?  If so, have we verified port
forwarding for tcp ports 80 and 443?

Right.  I think we *also* need to fix certificate issue.

Are you running wireshark on the freedombox itself?  If not, I'm not
sure I'd trust that packet dump.  Capturing unicast traffic that doesn't
involve the capturing host is tricky business [2].  Maybe try tcpdump on
the freedombox (via ssh)?
