AADSTS700084
What Microsoft says
The refresh token was issued to a single page app (SPA), and therefore has a fixed, limited lifetime of {time}, which can't be extended. It is now expired and a new sign in request must be sent by the SPA to the sign in page. The token was issued on {issueDate}.
How to fix it
Microsoft doesn't publish a specific fix for this code beyond the description above. This site groups it under app registration and tokens, based on that description, so start with the steps below.
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.
