Hello Engineers and Developers,

I'm currently deploying a three-nodes openstack controller cluster, controller-01, controller-02, anc controller-03. I have installed the keystone service on the three controllers and generated fernet keys on one node and distributed the keys to the other nodes of the cluster. Hence, I have configured an HAProxy in front of them that would distribute the incoming requests over them. 

The issue is, when I try to access the keystone endpoint from using the VIP of the loadbalancer, the service works ONLY on the node that I have generated the keys on, and it doesn't work on the nodes that got the keys by distribution. the error message I have got is "INTERNAL SERVER ERROR (500)"

In other words, the node that had keystone-manage fernet_setup command ran on it, it can run the service properly, but the others can't.

Is the way of replicating the key incorrect? is there any other way?

Thanks in advance
