Itch.io HTTPRequest fail (Godot)

I exported my game as HTML5 in Godot and everything works fine if I run it on a local server but when uploaded to itch.io and run I get HTTPRequest fail attempting to authenticate. Is there a reason for this and more importantly is there a fix?

Can you share the exact response code, error message, stack trace, and any other specifics that would help us understand the error you’re seeing?

It would also help to know where you’re running your server and how it’s been set up, but let’s start with the error details.
