Cannot display MongoLab data on Heroku deployed website

Question

I recently applied a genetic data application (using API 23andMe) to Heroku and integrated Universal SSL using Cloudflare. My data is stored in a free Sandbox plan using the MLab addon on Heroku. 23andMe data is stored in MLab. As soon as I added my site to Cloudflare, data was rarely displayed on the page. In 99% of cases, MLab data is not displayed, but in 1% of cases.

router.get('/tools/my-genetics', ensureAuthenticated, function(req, res) {
  var data = {};
  if(req.user) {

   SNPs.find({user_id: req.user._id}).then(function(result) {
    data.genes = result;


   })

   res.render('tools/gene_data', {
    data: data,
    user: req.user,
    layout: 'dash'
   });
  }
});

. if/else, .

router.get('/tools/my-genetics', ensureAuthenticated, function(req, res) {
  var data = {};

  SNPs.find({user_id: req.user._id}).exec(function(err, result) {
    data.genes = result;


    if(err) {
      console.log(err);
    }else {
      console.log('===result inside here===: ' + result);

      res.render('tools/gene_data', {
        data: data,
        user: req.user,
        layout: 'dash'
      });      
    }
  });
});
