When upgrading from OMV6 to OMV7, omv-release-upgrade stops with the following error:
W: Failed to fetch http://ftp.uni-hannover.de/deb…/dists/bookworm/InRelease Could not connect to ftp.uni-hannover.de:80 (130.75.2.22), connection timed out
W: Failed to fetch http://ftp.uni-hannover.de/deb…ookworm-updates/InRelease Unable to connect to ftp.uni-hannover.de:http:

The upgrade on the backup device on the same LAN, but in a different building, went through without a hitch. Here, omv-release-upgrade retrieved the packages from RWTH Aachen University.
Does anyone have any ideas?
