OK, I guess I’ve solved this myself :smile:

Checked the firewalld (bc of the last line of the protocol) --> inactive!
Started it.
Everything works fine again :slight_smile:

Sometimes nothing is actually broken. You’re just not smart enough :smirk:

Unfortunately it’s broken again :confused:

After updating to 20.20 the machine hung and I had again to hard reset by unplugging and replugging power.
After that I again experienced the 500 error because of a non-running firewalld.

But now I receive this after trying to restart it (systemctl status excerpt):

Dez 26 10:46:04 odroidxu4 firewalld[10964]: WARNING: ipset not usable, disabling ipset usage in firewall.
Dez 26 10:46:04 odroidxu4 firewalld[10964]: ERROR: INVALID_ZONE

I tried to restore firewalld from a former backup but that didn’t change the unusable ipset.

What now? How can I fix or regain the ipset?
