Power BI Error:
AADSTS135010

What does this error mean?

Microsoft Entra ID (Azure AD) cannot find the signing or decryption key referenced by your app's token or SAML configuration.

Common causes

  • 1The signing certificate on the app registration was rotated or expired and the old key is still being referenced
  • 2The app manifest's keyCredentials or tokenEncryptionKeyId points to a key that no longer exists
  • 3A service principal used by Power BI / ADF / Fabric authenticates with a client certificate that was deleted from the app registration
  • 4SAML SSO configuration references a token signing certificate that has been removed from Entra ID
  • 5Cached/old JWKS metadata on the client side after a key rollover, causing it to send a stale kid

How to fix it

  1. 1Open the app registration in the Microsoft Entra admin center → Certificates & secrets, and verify which certificates/keys are currently active and not expired
  2. 2Inspect the app manifest (Manifest blade) and confirm that keyCredentials and tokenEncryptionKeyId reference an existing, non-expired key — remove or update stale entries
  3. 3If a certificate was rotated, upload the new public certificate and update the calling service (Power BI service principal, ADF linked service, Databricks secret scope) with the matching private key
  4. 4For SAML/SSO apps, go to Enterprise applications → SSO → SAML signing certificate, and ensure the active certificate matches what the relying party expects; re-download metadata if needed
  5. 5Force a refresh of OIDC/JWKS metadata on the client (restart the app or clear the discovery cache) so it picks up the current key set
