Unable to create configMap noticer

[blues-man]

Hello, I'm following Documentation to instal Knative 0.2.0 but I have an issue on installing knative-eventing.

One Pod is always in CrashLoopBackOff:

in-memory-channel-dispatcher-c54844b75-zsj4v 1/2 CrashLoopBackOff 1 1m

and the error is:

  | {"level":"fatal","ts":1553688777.1088018,"caller":"fanoutsidecar/main.go:91","msg":"Unable to create configMap noticer.","error":"Get https://172.30.0.1:443/api?timeout=32s:  dial tcp 172.30.0.1:443: connect: connection refused","stacktrace":"main.main\n\t/go/src/github.com/knative/eventing/cmd/fanoutsidecar/main.go:91\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:198"}
-- | --

This issue is similar to this one:
knative/eventing#827

My env is:

OCP 3.11.88
RHEL 7.6

3 Nodes (1 Master 1 Infra 1 Node) all schedulable

Thanks

dial tcp 172.30.0.1:443: connect: connection refused - that looks like this pod can't reach the api server? Do any of your other pods have similar errors?

no error so far in other pods, everything is working fine in all other namespaces and all knative components but this.
