I am using keycloak for sso in spring boot application. It is working fine in single node environment.

But as I shift whole setup to HA in IPV6 environment, unable to authenticate spring boot application with keycloak.
Getting error whenever any spring boot application api is used.
Need some help on this. Two observations from my side:
1. https request rather than http.
2. 0 is appending in sso uri, making invalid uri.
