When doing a `sudo apt update`, all apt.tn.ixsystems.com sources reops will respond with a 502 Bad gateway. Others repos are working well (jellyfin repo for example). the repos were working fine 48 hours ago.

in consequence, it is not possible to update packages by apt.

on another device, if we try to curl [http://apt.tn.ixsystems.com/apt-direct/|http://apt.tn.ixsystems.com/apt-direct/angelfish/22.02-RC.2/angelfish] for example, it will respond with a 502. It seems that the repo organization have changed (no apt-direct folder in parent folder).
