We recently upgraded our infrastructure to the new Strato KVM VPS. After we had set up our dockerized services we noticed that none of our services are reachable through their defined ports. Neither from localhost nor from external. This happens with both podman and docker. Our images are working correctly. If we use the --net host flag everything works fine and can be reached but thats not what we want and should not be necessary. If you need more information feel free to ask.
We are grateful for any help.
Additional information:
os: ubuntu 22.04
podman: 3.4.4
cat /proc/sys/net/ipv6/conf/all/forwarding 1
cat /proc/sys/net/ipv4/ip_forward 1
