网站无法在手机上加载内容

Question

I built a web site by using Angular 2, NodeJS and Firebase and it works perfectly on localhost , however after I hosted it on Heroku ( link ) it isn't working on mobiles website. Does any one know what is the problem?

If you need some code I have it as well, can attach that part which you will need.

Thank you every one , i forgot middleware

app.use(function (req , res ,next) {
  res.setHeader('Access-Control-Allow-Origin' , '*');
  res.setHeader('Access-Control-Allow-Methods' , '*');
  next();

});

so it was reason why i could not access the page
