Restarting NGINX fails

I installed NGINX on Ubuntu 16.04 and edited my config. When I want to restart with sudo service nginx restart I get the error:

Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

The content of nginx.service status is:

nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Mon 2017-01-02 16:07:54 UTC; 15s ago

Jan 02 16:07:54 IF-STG-001 systemd[1]: nginx.service: Failed with result 'exit-code'.

Why can't I restart my nginx instance? I don't see why it is blocking the restart

This issue generally arises when you are running apache server on the same machine as apache and nginx need the same port to run i.e. 80. tried to change the nginx port to 8080 or something else. i.e. {listen 8080 default_server;listen [::]:8080 default_server;} and restart the nginx

The important part of the error message is

bind() to 0.0.0.0:80 failed (98: Address already in use)

Thus, when starting up, nginx could not bind to the port 80 since some other program is already bound to this port. You will only be able to start nginx when this other program exits or unbinds from this socket.

To find which program currently bind this port, you can run this command as root (e.g. with sudo):

ss -ntlp "sport = :80"
