invalid_client

ellisonrje

My instance began throwing an invalid_client error today for the Oauth2 configuration. The token has expired and it is no longer importing emails. I am on 1.18.1. I am looking through configuration and researching but so far am not finding anything. Any suggestions are welcome and if further information is needed to diagnose, please let me know.

What provider are you using? I would recommend going back through the OAuth2 Authorization documentation relevant to the provider you are using and just thoroughly double-checking everything. Then once you confirm everything is good I would try deleting the expired token (via the email’s Delete Token button within the Token tab of the Authentication Config popup) and attempt to retrieve a new one by submitting the popup. It’s important to make sure the URLs have not changed, make sure that the URL you are making the token call from matches the Redirect URI (all URLs and schemes must match), etc.

Cheers.

Thank you. I found an expired certificate that was used for the secret. Created a new certificate and updated the secret and I am back up and runnning.
