Fail to Run Standalone HA Mode in Cloud Foundary

Hi all,

I try to follow the instructions from and
but fail to do it. Only a single node can be discovered after running the command
[standalone@localhost:9990 /] /subsystem=jgroups/channel=ee:read-attribute(name=
“outcome” => “success”,
“result” => “[faa0d801-e90f-4d35-5a37-2c94|0] (1) [faa0d801-e90f-4d35-5a37-2
There is no exception. Do you have such experience on running keycloak HA on cloud foundary or PCF? thanks.
