The problem is very likely the Application Controller.

You can restart it:

shell

kubectl rollout restart sts -n argocd argocd-application-controller

Or inspect its logs:

     shell
     
kubectl logs -n argocd argocd-application-controller-0 --tail=100 | less

While we’re here, make sure there is at least one replica running:

% kubectl get sts -n argocd argocd-application-controller
NAME                            READY   AGE
argocd-application-controller   1/1     415d
