You can use 'reconnectTries' & 'autoReconnect' parameters to make your connection retry forever. Update your mongo connection code to the following

var db = {};
var mongoDbUri = "mongodb://db_user:[email protected]:27017/db_name";
var settings = {
      reconnectTries : Number.MAX_VALUE,
      autoReconnect : true
MongoClient.connect(mongoDbUri, settings, function(err, dbref) {
  if (!err) {
    console.log("Mongodb connected");
    db = dbref;
    console.log("Error while connecting to mongoDB" + err);
