Connection refused When I using browser with other port

I can access my host with browser using 80 port, but I get Connection refused when I access my host with other port (like 8080, 81, 82.....). How can I expose more port to access my services?

the output of netstat -lnp as below:

Active Internet connections (only servers)

Hello,

If you have your UFW enabled, you can open ports with the following command:

sudo ufw allow 8080

Also I can see that you are using Docker, you need to make sure that you expose the port that you are trying to access, for example:

docker run -d -p 8080:8080 ID

This would expose port 8080 on the host and forward it to the container.

Hope that this helps!
Regards,
Bobby
