Unfortunately, I can't reproduce it on a test VM, from which the configuration
was created, nor on two live systems, that run similar setups.
For reference, this is a prototype VM:

I've started from that, as it was more than just a momentary "hey, let's run
some containers!" idea.
Unfortunately, whatever is happening, happening only to that one live system.

I know :) Your help is nonetheless appreciated.

I did mean an alternate login to the host. Which is a little less convenient
to use (it is key-restricted), but allows me to login in the events like this,
when domain controller is unavailable for whatever reason.
