[FIXED] Why docker container on specific port return connection refused?

Issue

I have a Linux VPS with docker installed, I ran an Nginx docker container on a specific port using flag -p, when I try connecting to it using VPS_IP:PORT always get Connection_Refused.

even using curl http://localhost:PORT return connection refused.

Except for port 80, every other port refuses to connect, though ufw is disabled.

docker container command I used:

docker container run -d -it -p 83:83 --name container_name -v /home/.../:/container_path/ nginx

Any thoughts on how to solve this problem?

Solution

Correct docker container command is :

docker container run -d -it -p 83:80 --name container_name -v /home/.../:/container_path/ nginx

Because Nginx docker image is listening on internal port 80
