I haven’t used iptables, but looks like you have a configuration problem:
Nov 26 15:29:05 OSMCV4K netfilter-persistent[2039]: iptables-restore v1.8.2 (nf_tables): Couldn't load match `owner':No such file or directory
Nov 26 15:29:05 OSMCV4K netfilter-persistent[2039]: Error occurred at line: 6
Nov 26 15:29:05 OSMCV4K netfilter-persistent[2039]: Try `iptables-restore -h' or 'iptables-restore --help' for more information.
Nov 26 15:29:05 OSMCV4K netfilter-persistent[2039]: run-parts: /usr/share/netfilter-persistent/plugins.d/15-ip4tables exited with return code 2
Do you really need iptables? Since it appears that it’s not working, maybe just remove it?
Also, have a look at this post. It may be related:
