Hi everyone,

I hope you will be able to help me about a strange behavior I have 🙂

I’m testing Keycloak in a cluster context (domain).  
I builded 2 local VMs (VirtualBox) on my computer:

- OS: Ubuntu 20.04 LTS
- Keycloak version: 16.1.0
- no firewall

Details about VM 1/2:

- 1 \* domain controler (port 9990)
- 1 \* host controler
- 1 \* server (port 8180)

Details about VM 2/2:

- 1 \* host controler
- 1 \* server (port 8180)

I builded a PostgreSQL database to share “objects” (don’t know if the word is the right word) between my 2 servers.

In HAL Management Console \> Runtime \> Topology I can see everything I configured and it’s green.

Scenario 1:

- I connect to the Keycloak 1/2 (\<IP of VM 1\>:8180/auth)
- I connect to the Keycloak 2/2 (\<IP of VM 2\>:8180/auth)
- from Keycloak 1/2 I create a user
- from Keycloak 2/2 I can see it directly  
 → it works as expected

Scenario 2:

- I connect to the Keycloak 1/2 (\<IP of VM 1\>:8180/auth)
- I connect to the Keycloak 2/2 (\<IP of VM 2\>:8180/auth)
- from Keycloak 2/2 I create a user
- from Keycloak 1/2 I can see it directly  
 → it works as expected

Scenario 3:

- I connect to the Keycloak 1/2 (\<IP of VM 1\>:8180/auth)
- I connect to the Keycloak 2/2 (\<IP of VM 2\>:8180/auth)
- from Keycloak 1/2 I create a new Realm
- from Keycloak 2/2 I can’t see it directly: I need to reload the server from HAL Management Console  
 → it doesn’t work as expected

Scenario 4:

- I connect to the Keycloak 1/2 (\<IP of VM 1\>:8180/auth)
- I connect to the Keycloak 2/2 (\<IP of VM 2\>:8180/auth)
- from Keycloak 2/2 I create a new Realm
- from Keycloak 1/2 I can see it directly  
 → it works as expected

Is someone knows why Scenario 3 has this behavior?  
I expect to be able to create objects / to configure my keycloak from any instance without having to reload all other instances 😕

It’s probably a parameter in my configuration file but I confess I’m lost 😕

Thank you very much 🙂
