Question project opens in local but hang in server

I'm trying to deploy a Unity WebGL game to VPS using an express server. When I run the express server locally, the game runs fine without errors, but when I upload to vps, it freezes after loading the content without showing any errors. I've also tried using a new empty Unity project just to make sure the problem is not linked to my code

network files
console logs

 

Have you tried clearing the cache?

 

yes first thing I did

 

can it be a problem with the server ? here are the nginx config and express route

 

It's the browser cache, not the server

 

I cleared cache , tried different browsers even different devices all with the same result
