[keycloak-user] Unable To Add Server to Existing Keycloak Cluster

[Sagar Ahire]

Hello,

I'm trying to add/start one more server to our existing keycloak cluster of
two nodes. I took the AMI snapshot of current running server and tried to
launch new keycloak service keeping the same configuration but getting the
following errors.

I'm using
*Keycloak version: 2.4.0*
*Wildfly version: 2.0.10*
