MongoDB connection timeout

http://stackoverflow.com/a/39603895/2177408

Error: 

 { [MongoError: connection 39 to 127.0.0.1:27017 timed out]  name: 'MongoError',  message: 'connection 39 to 127.0.0.1:27017 timed out' }

Solution:

var options = {   server: {     socketOptions: {       keepAlive: 300000, connectTimeoutMS: 30000     }   },   replset: {     socketOptions: {       keepAlive: 300000,       connectTimeoutMS : 30000     }   } };

Then put it in here:

if(process.env.MONGODB_URI) {  mongoose.connect(process.env.MONGODB_URI, options);} else {  // Connect to local database}
