I have no knowledge of this specific issue but 403 means unauthorized and the “Just a moment” response is usually because the server sends a JavaScript challenge to verify that you are a ‘real’ browser/user. It’s an anti bot verification and you’re not passing.
Not sure what your question is or how people will respond, but in my opinion, asking for advice from someone with more experience isn’t as shameful or ‘dumb’ as you might think.
