onbeforeunload - beforeunload Event in ReactJS Not Working on Server

Question

I have a ReactJS app in which I am using the beforeunload event to determine when a user leaves the page (either by closing the tab or the window). Code I am using is:

window.addEventListener("beforeunload", () => {  
  //Update active user count
});

This is to keep a live count of how many users are on a specific page for a dashboard. The page can be accessed by anyone and does not require logging in. This code works fine with I run the application locally, but once I deploy it to the server it does not run the event.

Any reason this would be fine locally but not when deployed?
