Hi, my first guess would be permissions. Did you check if the directory and files have the correct permissions? How did you distribute the keys? Zitat von Taha Adel <eng.taha1928@gmail.com>:

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
