[keycloak-user] Kubernetes: found IPv4 multicast address in an IPv6 stack

[Lukasz Lech]

Hello,

I was succesfully running Keycloak as docker image (4.8.1), however, when I try to run in Kubernetes, I'm getting the following error:

07:53:34,742 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 52) MSC000001: Failed to start service org.wildfly.clustering.jgroups.channel.ee: org.jboss.msc.service.StartException in service org.wildfly.clustering.jgroups.channel.ee: java.lang.IllegalStateException: java.lang.Exception: found IPv4 multicast address /230.0.0.4 in an IPv6 stack

Server seems to listen, going to / returns redirect to /auth, but going to /auth results in 404, no further error lands in logs...

Anyone has any idea what it can be?
