Issue with The Scoop: Browser Clicks not recognised in my JavaScript Script

Hello,
I’m having a problem with the Project The Scoop (https://www.codecademy.com/paths/create-a-back-end-app-with-javascript/tracks/bapi-javascript-objects-modules-and-browser-compatibility/modules/the-scoop/informationals/the-scoop)

I’ve written all the code in my server.js file and the test suite doesn’t report any issues, but when I open the index.html file in Google Chrome (v80) and start the server from bash, the “The Scoop” Start Page (Meaning the Header and no Articles) appears, but when I try to log in (as shown in the video) and i click the “LOGIN” Button, nothing happens.
This is also the same with the Solution Code, so I think there must be an error not in my Code, but in any settings or whatever.

Can anyone give me a hint to guide me in the right direction? I have absolutely no idea what to look for.
