Node.JS HTTPS server prevent default HTML

I deployed a Node.JS HTTPS server, and it loads my frontend, but the issue happens when I click on a form on my frontend, it screws up.

   var fs = require('fs');

    var options = {
      key: fs.readFileSync('./key.pem'),
      cert: fs.readFileSync('./cert.pem')
    };

var server = http.createServer(options, app);

In my frontend, I specifically have prevent default, but it does something like:

https://localhost:8443/?u=q%40q.com&p=qqqqqq

But when I have an HTTP server, it works perfectly. What is the issue?
