Most Dockers not accessible after upgrade to Ubuntu 22.04


I’m running docker with several containers in a Ubuntu 20.04.

If I upgrade it to 22.04 and upgrade the docker components for 22.04. I can see that the containers are up, but most of them are not accessible via their ports. I believe it has to do with nftables. Be that as it may, I could not solve the issue.

The ufw is disabled, but I’m not sure what I have to do in order to make it work.

This is a lab environment at home with no access from outside world.

Any help is much appreciated
