Authorization Issue

The error displayed on the plugin page:
invalid_grant AADSTS54005: OAuth2 Authorization code was already redeemed, please retry with a new valid code or use an existing refresh token. Trace ID: 1bbf59c6-5e03-4829-8575-5fb577997700 Correlation ID: a8f59c80-054d-4bc9-ac40-9bb5e670cbf7 Timestamp: 2022-01-19 13:38:10Z

@cgoro so you are loading the settings page with the old authorisation code still within the URL. Clear the settings page URL of any URL parameters (that’s everything after the ?) and reload the page. Once it’s loaded, try the authorise button again.

@cgoro the other thing you could check (having read this guide: https://docs.microsoft.com/en-us/answers/questions/311300/oauth2-authorization-code-was-already-redeemed.html) is that your client secret hasn’t expired.

The expiry time is set when you create the secret. If you chose just a few months this might explain the error. If it’s expired, you will need to create a new secret and copy this into the plugins settings area.

The secret value has not expired.
I have cleared the settings URL of any parameters but the Fatal Error is still recurring when I attempt authorization.
The second error about the invalid grant is no more.

@cgoro so I would make a note of the Client and Tenant ID’s then untick the option “Keep OAuth Credentials” in the plugin settings page (if it isn’t already unticked). I’d then deactivate and reactivate the plugin.

Re-enter the client and tenant ID’s and regenerate a client secret from within the Azure App settings on the Azure AD Portal (id delete the old secret as well).

Save the settings and then reauthorize. This process should clear all the old values from the database.

@cgoro I assume, as it’s been over two months that this was fixed so I’m closing.

The issue was resolved
