The error occurred because the client secret used by our service principal for the Azure AD (Microsoft Entra ID) integration had expired.
A client secret acts as a password that allows our application to authenticate and communicate with Microsoft Entra ID. These secrets are intentionally configured to expire after a set period for security reasons. When the secret reached its expiration date, authentication attempts began failing with the error:
"The provided client secret keys for app are expired."
We have generated a new client secret and updated all affected systems. We scheduled the next renewal to prevent this from happening again.
