Developer Forums - Page Not Found when signing in with my Apple ID

For context, I've just recently started my Swift Development journey. I encountered a weird glitch when using the visionOS Xcode Simulator and I wanted to ask the developer forums, if it's an actual issue or just a poorly written model in my codebase.

For some reason though, whenever I try to sign in the dev forums with my Apple ID I get a "Page Not Found" error, just after submitting my details. I've tried on my home wi-fi as well as an ethernet cable and even tried sharing a hotspot from my iPhone.

Any clue what might be causing this - or how to get around it?
