Description

I have upgraded from nifi version 1.12.1 to 1.13.2. After the upgrade, the cluster load balancer does not work properly and then flowfiles get stuck on queue. Then the weird thing is that I can't see any error on logs.

I've tried to downgrade java from 11 down to version 8 but still same issue exist.

My nifi cluster has three nodes deployed on a GCP VM.
