checkquestion: does your compute have a public IP ( is it situated in a public subnet?)
That's one of the prerequisits

Yes, OCI automatically provides public ip to new instance and I used provided ip address.

Hi everyone!
I'm facing the same problem. I created an instance to run my server which requires port 4665. I run the server but I can't access it from outside world. The server-client was tested in a private network and it worked perfectly. It's kind of WebSockets server, I also tried to run it on ports 80 and 443, with no success, I got: "Error on bind [13]: Permission denied". I even tried ports 50000+ but I still can't connect.
I opened several ports to run aaPanel and it works like a charm but I can't have my server work.

Linux shows me that my desired port is open with "LISTEN"
but still no connection from outside world.
Any idea?

Try to the add the ports to the public zone:

$ sudo firewall-cmd --zone=public --permanent --add-port=80/tcp
$ sudo firewall-cmd --zone=public --permanent --add-port=443/tcp
$ sudo firewall-cmd --reload

Hi Adrian,
result of

$ sudo firewall-cmd --zone=public --permanent --add-port=443/tcp

as per attached pics.

I musked my external address and remote address for safety sake.
With regards

Unexpected result was found when deployed docker app to my OCI instance to which I have not been able to open 443 nor 8080. The docker app was constructed by following Dockerfile.

  ============
  After this deployment, the port check service showed port 8088 was opened and therefore I succeeded to open the web app through port 8088.
  It is something a inscrutable mistery
