[keycloak-user] Unable to log in to admin console Keycloak 3.4.1

Hi all, I've recently upgrade the version of Keycloak we're running from 2.5.5 to 3.4.1. In a single instance environment everything works fine. In a clustered environment, when I try logging in to the admin console, I'm logged out again as soon as I've logged in. It seems like I'm logging in to one cluster instance successfully, but then I'm sent to a page on another instance and my session information hasn't been shared with that instance so it kicks me out. This worked fine with 2.5.5. I've attached the standalone-ha.xml I'm using. Kind regards, Phil Evans
