Rather than start a new thread, I'll add to this one. I appear to have the same issue, launcher.log returns:
I use 1.1.1.1 w/ encrypted DNS but I don't use a proxy so highly doubt that my net config is the cause of the 403
I'm hearing about a server migration of some kind so I wonder if this is related
