Some pods failing afte kubeflow-lite installation

After kubeflow-lite installaton juju status gives me information below.

There are two dex-auth unit. One fails, and the other is “waiting for leadership”

dex-auth/4* error idle 10.1.85.178 5556/TCP hook failed: “ingress-relation-broken” dex-auth/5 waiting idle 10.1.85.185 5556/TCP Waiting for leadership

kfp-schedwf/1*, kfp-viz/1*, and admission-webhook/1* are waiting for leadership.

Morever, I have the logs below. Could you please help me how I can solve these problems?
