@roafh This is probably related to the
increased login and signup errorsthat are currently being reported on the OpenAI status page. I'd recommend watching that page and trying again after the issue has been resolved.It could be caused by your browser extensions. I had the same issue and I used Microsoft Edge with no extensions and it worked.
