can no longer load express app webpages - node.js

Question

So i've been working on getting a user authentication system going and then I encountered a problem where my webpages would no longer load. npm start works fine and the server appears to be running. going to localhost just shows that the bar keeps loading and never eventually loads (before the webpages loaded instantly). I have no idea what I changed but tried to revert as much of the code to the original but still no dice. let me know if any other files are needed. thanks in advance
