Re: [keycloak-user] Standalone-ha Keycloak and ISPN000476: Timed out waiting for responses for request

Thanks for the prompt reply. To answer you: It is the standard configuration, so, this should not be a problem. - Faulty NIC or incorrect network level configuration in the datacenter Maybe? Well, both VMs are in the same broadcast domain, and there is no firewall in-between them. Here go some log entries. There are some things that I do not understand here. Why am I seing multiple “keycloak-1: installing view”? Shouldn't it only happen once? The same situation is happening with “created cluster (first member). My view is [keycloak-1|0]” 2018-10-24 14:48:02,138 DEBUG [org.jgroups.protocols.pbcast.STABLE] 2018-10-24 14:48:02,155 INFO [org.infinispan.CLUSTER] 2018-10-24 14:48:03,271 INFO [org.infinispan.CLUSTER] On Wed, Oct 24, 2018 at 10:29 AM Sebastian Laskawiec <slaskawi(a)redhat.com&gt; wrote: > The new view log messages look a bit weird.
