ArgoCD on ECS instance: how to connect private gitlab repo?

Hi, I'm newbie.
I have an instance in ECS and I deployed AgroCD on it.
I need to configure repositories of ArgoCD to connect to my private gitlab repository. But I can not. When I log pod argocd-server, I receive this


" level=warning msg="Failed to resync revoked tokens. retrying again in 1 minute: dial tcp: lookup argocd-redis on 127.0.0.53:53: read udp 127.0.0.1:50534->127.0.0.53:53: read: connection refused" "


Please help me
