So the buttons are not working for example page and other things load but the js script or idk what but its not working this is the github link of my test site https://github.com/furjac/fg-buzzer
this works flawless when i use in node index.js locally
this is the site vercel hosting https://fg-buzzer.vercel.app/
there is no index.html so you have to directly goto /user.html or /host.html or /board.html

I want this site working have a quiz contest soon so creating this to use it on that day thanks in advance
