My identity provider was previously working, but now is going to this page https://[website]/Account/Login/ExternalLoginCallback?ReturnUrl=%2Fen-US%2FAccount%2FManage%2FChangeLogin%3FMessage%3DLinkLoginFailure&Provider=Microsoft&error=access_denied
With error:
"Unable to authenticate with the external account provider."
I've seen a few similar posts. Any fixes? I've tried deleting and reconfiguring.
