Problem
You see the following error while attempting to authenticate with WHMCS using Google® Sign-In Integrations:
Verification for current settings failed validationResponse: {valid:false}
Cause
The Authorized JavaScript Origins and Authorized redirect URIs settings are incorrect or the WHMCS System URL setting is using an insecure http://
connection.
Solution
Check to ensure that the settings in Google are valid and that your system uses a properly-configured SSL certificate.
