Hello, I am trying to install NodeBB onto my Ubuntu 16.04 server.
I am using AWS with a Ubuntu 16.04 AMI and have installed Node.js and MongoDB on Nginx
When I type ./nodebb start to start NodeBB, it says

But When I go to my url and port number, the site cannot be reached.
I am stuck, help please!
Here is a copy of my config.json file
{
"url": "http://myPublicServerIP",
"secret": "",
"database": "mongo",
"port": "4567",
"mongo": {
"host": "127.0.0.1",
"port": "27017",
"username": "nodebb",
"password": "myPassword",
"database": "nodebb"
}
}
And this is the output when I type ./nodebb log :

Thank you.
