we are currently running a three node standalone cluster of vro 8.6. Our loadbalancer monitor receives a 500 based on the official loadbalancer configuration which results in the whole cluster being unaccessable. When investigating a single node and requesting the same health check we receive the same error.
I have migrated the cluster to a single node hostname to confirm that anything is still working which is the case.
We restart all nodes multiple times and did clean deployments which didnt help at all.
