AADSTS70000
InvalidGrant
What it means
Authentication failed because the refresh token isn't valid.
How to fix it
Sign in again.
How to investigate
- Compare what the app sends (client ID, redirect URI, scopes, tenant) with the app registration.
- Decode the token or request: the JWT and SAML decoders on this site show exactly what was sent.
- Check the app's credentials (secrets and certificates) and whether the service principal exists and is enabled in this tenant.
- Search the sign-in logs for the request ID or correlation ID from the troubleshooting details on the error page.
