does anyone know where I might look for these errors?
unfortunately, the error text doesn’t really point me to any area atm :frowning:

seems that I’ve found the issue.

I don’t know why, but Supervisor did show an IP configuration with /32 for subnet mask.
After changing this to /24 it seems to be resolved.
