Why doesn't a Node JS site open in mobile browsers if Content-Length is greater than a certain value?

Question

Node.js

If the Content-Length is greater than about 1600, then the page does not load on a mobile browser (chrome, firefox) (no error, just waiting for a response). On the desktop everything is OK!
PS There is nothing suspicious in the Chrome debugger (debugger on mobile chrome).

Answer 1

Is there a web server? Or is nodejs giving the data directly? Have you tried to check on a static large html file?
