Sign In Failed with macOS Sequoia 15.2 ChatGPT Extension in System Settings

Whenever I try to log into the macOS integrated ChatGPT extension. Located in the System Settings. I keep getting a Login Failed return. I have tried with VPN, without VPN. I have reinstalled the OS without improvement. I have turned Apple Intelligence off and back on again. Nothing seems to work. However, if I log in on another machine I have, same place, same credentials. It works. Any help or advice would be appreciated…
