How to make eJabberd XMPP Server work? (in droplet with nginx/php/maridb/tls already running)

I already have a droplet running Nginx/Php/Maridb with TLS(https). It works just fine. Then i tried to install eJabberd XMPP Server in the same droplet using this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-ejabberd-xmpp-server-on-ubuntu The installation works fine. I run “service ejabberd status” and it says it’s running, BUT it doesn’t work. I can not open the http://(or https://)<my droplet ip>:5280/admin or 5222 or 5223… It just doesn’t return anything. Am i doing something wrong here?

– after “sudo netstat -plutn”:
