The infrastructure pods are deployments that run replicas. You will have to determine which replica is the leader and check its logs for the latest. A non-leader will usually stop after logging something about attempting to acquire the lease.
You will need to log in to Supervisor and use the Supervisor vSphere Namespace to check these pods.
