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) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0* LISTEN 28886/php-fpm.conf) tcp 0 0* LISTEN 1666/sshd tcp6 0 0 :::3306 :::* LISTEN 15739/docker-proxy tcp6 0 0 :::2222 :::* LISTEN 14782/docker-proxy tcp6 0 0 :::8080 :::* LISTEN 15942/docker-proxy tcp6 0 0 :::80 :::* LISTEN 15161/docker-proxy tcp6 0 0 :::22 :::* LISTEN 1666/sshd tcp6 0 0 :::443 :::* LISTEN 15150/docker-proxy

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
