    The cause: There could be a problem with the configuration file.

    The solution: To discover any issues in the configuration file, use the nginx -t -c /etc/nginx/nginx.conf command. If the bugs are fixed, restart nginx with sudo service nginx restart. It’ll work out.

  2. A process is already bound to the HTTP Port . (Especially after upgrading systems!) It will automatically start apache2 by default

    This is the first time you try it: 

    sudo service apache2 stop

    To resolve the problem, run the sudo lsof -i:80 command to see a list all processes that use port 80. Next, disable server.

    Stop the process that uses the port 80 

    sudo fuser -k 80/tcp

    It could be a problem in the configuration file.

    To find any missing configuration, you can use nginx -t -c /etc/nginx/nginx.conf command

    This error can sometimes be caused by Nginx sites that are already running on port 80. If you don’t have one, it is possible to remove default config. 

    sudo rm /etc/nginx/sites-enabled/default
sudo service nginx restart
