I have a problem accessing Docker containers for any other port than 80. Previously it worked and I had services accessibles on ports 5000 and 7000 in addition to a nginx server installed directly on the droplet. I recently do a dist-upgrade to Ubuntu 18.04.1 LTS and that may have broken stuff.
What doesn’t work:
So it seems there is a problem with other ports than 80 and 443 for serving content on the internet. I have no digital ocean firewall configured. I tried to look iptables stuff but I understand very little and don’t manage to find anything suspicious.
I would need your help to solve this case.
