Rancher HA - Istio installation hangs


I have set up a 3-node HA-cluster with Rancher and now want to deploy Istio.

First question: as there are two possibilities do deploy Istio being via Tools->Istio->Enable or via Apps->Launch-> Istio, what is the prefered option?

Installing Rancher the first way, the Istio page stays on Status “Installing Istio into the system project of current cluster…”. Navigating to the Istio-App in System project, I see the app has status “Installing” and clicking on it there appears the message “Failed to install app cluster-istio. Error: Job failed: BackoffLimitExceeded”.

I dont’ see any failed pods…

Accessing Jaeger gives me simply the message “Error”. Looking in the logs of istio-tracing I don’t see any error messages.

How can I debug this?

Many thanks in advance!
