So far I’m unable to reproduce this at all. Can you post your full output from ip a without redactions?

Ok, my apologies. One reboot and everything is back up again. I didn’t want to do this at first as this is quite critical service here, but decided to do it anyway since you couoldn’t reproduce.

Thx for the quick replies!
