`Error: not_a_saml_app` is what google barks back up when testing and trying to log in.
Followed all the steps listed here: https://support.solarwinds.com/SuccessCenter/s/article/How-to-log-in-to-Web-Help-Desk-using-Google-G-Suite?language=en_US
Not sure how to debug this issue further?
This is the same error described in the comments here: https://thwack.solarwinds.com/product-forums/web-help-desk-whd/i/feature-requests/google-apps-authentication---webhelpdesk?CommentId=05cdb7e7-b85b-42a9-800a-13d5e75a8707
My site didn't start working again though.
