Cluster_controller process, its ApplicationLoadBalancer domain name can't be resolved by DNS server

I encountered a weird case. If I created my cluster with 1 cluster_controller being defined in cluster CR, then using ALB for this cluster(only for cluster_controller processes, proxy processes and storage processes), I could see that the resolution of cluster_controller process’s ALB domain name was being hung.
But if I created my cluster with no cluster_controller process being defined in CR, the resolution of other processes, such as proxy and storages, can be executed timely and successfully.
Is there anything special with cluster_controller if I create ALB for it?

Could you share some more information e.g. operator version, FoundationDB Cluster spec. I’m not aware. of any special steps regarding the cluster controller in this case.
