How to configure CentOS-vServer to support REST Calls on domain-name running Spring Boot on Port 8080

i have the domain www.abc.com registered and forwarded via DNS-A-Record to my vServer 111.222.333.444 running CentOS 7.

I have a jar-File containing a fully working Spring-Boot Application answering REST Calls on Port 8080.

The Problem is, whatever I do, i can’t manage to make it work.

I want to do this:

www.abc.com/status or www.abc.com:8080/status to get a response

it works locally with localhost:8080/status but not from outside via my domain.

Can you please help me?

    If you want to access http://www.abc.com/status the you have to run the application on port 80 or add a reverse proxy like nginx or Apache HTTP server in-front of your application.

    If you cannot access http://www.abc.com:8080/status you should check if there are any firewall settings that don’t allow access to port 8080 resp. only allow access to port 80 and 443.

    You can use port forwarding on your machine using iptables.
    it is explained in other posts e.g here:
    iptables: Duplicating/Forwarding ports

    Simon’s observation regarding to firewall is correct for this solution too.
