Hey Lukasz,
The clustering probably won't work in your setup. In other words, if you'd
like to add another Keycloak node to ensure HA or balance the load, that
won't work.
I guess, you're using IPv4 network in your datacenter, aren't you? If so,
please add -Djava.net.preferIPv4Stack=true switch to Keycloak to ensure,
JGroups use IPv4.
Thanks,
Sebastian

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:

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?
Best regards,
