SSO using dex and google groups is not working

[alonbnhubsecurity]

Hello,
I am trying to add SSO with Google to my ArgoCD.
I followed this documentation but It doesn't work for me.
Whenever I press the LOG IN VIA GOOGLE button it just redirects me to the login page (back to https://argocd.my-domain.com/login?return_url...) and gives me the following errors:

GET https://argocd.my-domain.com/api/v1/clusters 401

Log in with admin works fine.

The dev-domain.dev is the domain that we use for our GCP account.
I enabled both domains in the GCP app.
As for permissions for the SA user I created, I gave it Organization Administrator in the meantime as it does not really specify what kind of role it needs and I didn't want to have permission problems.
After every change I reset the argocd-dex-deploument.

The ArgoCD version I am using is v2.6.7+5bcd846 based on github.com/argoproj-labs/argocd-autopilot/manifests/insecure?ref=v0.4.2.

GKE version 1.25.6-gke.1000 and updated to 1.25.7-gke.1000

Trying to login with cli and sso give me the following:
FATA[0000] Failed to query provider "/api/dex": Get "/api/dex/.well-known/openid-configuration": unsupported protocol scheme ""

Please help me troubleshoot this problem,
Let me know if you need me to add more information.
