I can't connect to my mongodb from socket.io. When I run my server.js it says that it is connected with mongodb and that it is connected to a socket but then it shows the error

MongoError: not authorized on db to execute command find.

I have loged in as an admin user into the mongo admin database, then went to the "chat" db and there created a new user in the database with the role "readWrite" like this.

use chat

and then:

db.createUser({user: "testuser", pwd: "testuser", roles: [{role: "readWrite", db: "chat" }]})
Successfully added user: {
    "user" : "testuser",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "chat"
        }
    ]
}

The user gets created. And when I test it with db.auth("testuser","testuser") I get a 1. I then exit and go to my bin folder and there I write:mongo.exe -u testuser -p testuser chat;

And then it connects to mongodb://127.0.0.1:127017/chat

I then open a new prompt and go to my folder where I have the server.js that connects with the db and run it, it then first says that the server is running and that it is connected with the mongodb.

When I the go to my chat page and load it then it says that: MongoError not authorized...

I connect my server.js file like this

var port = process.env.PORT || 3000;
server.listen(port);
console.log('Server running *:'+port);

var io = require('socket.io').listen(server);
var mongoose = require('mongoose');

//mongoose.connect('mongodb://127.0.0.1:27017/chat', function(err){
mongoose.connect('mongodb://localhost/chat', function(err){

I don´t know what Im missing, I have followed the docs on mongodb and looked all over the net, but not sure where I go wrong.

Any input really appreciated thanks.

When I load the chat page and look in the console I get this error.
