We are looking for guidance with an error we are seeing in our logs relating to single sign on with Office 365 and our cloud hosted app which allows users to sign in using their Office 365 credentials.
Failed login attempts Error messages in logs and we get emails O365OAuthCallback These always result in a paired of errors in our logs: Error code AADST70002 and AADST70011, Invalid credentials and invalid and the extended message says OAuth doesn’t match reply address.
Our logs show users are able to log in and no customer has ever raised this with our support team. In spite of many attempts we have never been able to replicate the issue ourselves.
Is this a warning, a rate limit exceeded or a quota exceeded? What’s the best way to troubleshoot this? All guidance appreciated.
