How can i visit my nodejs website without typing :8080 or :8000? : I have an ubuntu 16.04 server with plesk installed with nodejs because it is written in angular2.
At the moment I'm runing the page with `http-server .` on my ubuntu server.
When i'm typing the ip address with ip:8000 or www.page.de:8080 I can visit my page.
But when i just type the ip address or www.page.de I see only a white page.

How can i change this?

Thanks in advance^^
