I recently deployed a version 4.5 OKD cluster and everything seems fine, but I can't get the Google identity provider to work for signing in. I followed the instructions here, but with no success. When I try to log in with my company google identity I get a very generic error message:

login error

I ended up with the following OAuth config:

spec:
  identityProviders:
  - google:
      clientID: <my-ID>.apps.googleusercontent.com
      clientSecret:
        name: google-secret
      hostedDomain: <company domain>
    mappingMethod: claim
    name: googleidp
    type: Google

I set the google project up as described too. Just created Oauth2.0 credentials, call back URL (which is correct since I get back to OKD after consent screen), no extra scopes in consent; just profile, email and openid, and OKD is not requesting any other scopes. The project is set to internal so only company users can log in.

After some investigations I managed to increase verbosity on the oauth-openshift pods and here is what is seen in the logs for a failed attempt:

I can't find a reason for the Unauthorized error so any help is much appreciated.
