EDIT:: found the problem, this is an internal docker iptables issue, restarting docker service solved it

Yes, as you discovered the Docker IPTables rules had been removed.

It it causes an issue again (eg when you restart the server), look for any custom scripts you may have that manipulate iptables. They may be flushing all rules before applying their setup, and that will break Docker’s networking.
