Good morning.
I had a docker swarm environment in a RHEL 7 aws server.
I upgraded the server to RHEL8 (to be precise AlmaLinux 8).
The swarm restarted correctly but I have a single problem.
A container exposes a web service on port 443 but I can’t reach it from outside the server. It’s reacheable only If I do a tunnel.
Can somebody help me with this network issue?
Thanks a lot.
Did you get help since then? If you can accesss the port through a tunnel on the same IP, that is likely a local firewall issue. I don’t use Alma Linux and it is not officially supported by Docker, but if any additional firewall rule was added or new packages installed after the upgrade , that could break the connection.
