ZeroTrust Warp -> Gsuite error

I am not able to enroll additional users or devices with my ZeroTrust account after installing WARP on their workstations.
The environment was setup before I started so everything was existing before I began working on it. I have followed the documentation for setting up a third party identity provider, the google account has already been set up and when I test it I get the following error:

GSUITE ERROR: Failed to refresh token
“error”: “invalid_grant”,
“error_description”: “Bad Request”

I don’t know where to begin with troubleshooting. Is this a Cloudflare issue or a Google issue? Where do I start?
