Description of problem:

Login via Keycloak is broken when the provider is changed from dex to keycloak **

Workaround

Restart argocd-server pod

Prerequisites (if any, like setup, operators/versions):

GitOps operator installed on the cluster (Tested with version v1.8.0+)

Steps to Reproduce

1. Remove dex configuration from ArgoCD CR
$ oc -n openshift-gitops patch argocd openshift-gitops --type='json' -p='[\{""op"": ""remove"", ""path"": ""/spec/sso"" }]'

2. Add to the ArgoCD CR : ($ oc edit argocd -n openshift-gitops)
**

spec:
  extraConfig:
    oidc.tls.insecure.skip.verify: 'true' 
  sso:
    provider: keycloak
    keycloak:
      rootCA: ""---BEGIN---END---""

3. Restart argocd server pod
$ oc rollout restart deployment.apps/openshift-gitops-server -n openshift-gitops

Wait for keycloak-1-deploy pod in openshift-gitops namespace to be Completed

Navigate to Networking -> Routes in openshift-gitops project and click on the link that takes you to the ArgoCD UI page

Up on clicking LOG IN VIA KEYCLOAK, the page refreshes and nothing changes

Actual results:

dex pod logs:

Failed to query provider "https://argocd-server-argocd.apps.ci-ln-55sjckk-72292.gcp-2.ci.openshift.org/api/dex": Get "https://argocd-dex-server.argocd.svc.cluster.local:5556/api/dex/.well-known/openid-configuration": dial tcp: lookup argocd-dex-server.argocd.svc.cluster.local on 172.30.0.10:53: no such host 

Expected results:

Login should succeed without having to restart the server pod

Reproducibility (Always/Intermittent/Only Once):

Always
