In your screenshot dex is running, not crashing, can you provide more information on your installation steps, and the yaml of the dex Deployment?

I have installed using manifest file from https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml and I ran kubectl apply -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml.. I am not getting the exact solution some time it work and some time doesnt work. Last week what I did I deleted argocd-dev-server pod by running "kubectl delete pod argocd-dev-server" and new pod gets created now its working fine. Could you please help me why some time its work for me and sometime it doesn't and this is not for first time.

Can you provide:

• Live Dex Deployment YAML (kubectl get (...) -o yaml)
• Logs from Dex container
• Output of kubectl get events -n (namespace)

Based on the Deployment status, it appears the Deployment is not in crashloopbackoff.
