Ha-cluster-init fails OpenSuse Leap 15.5

I am trying to setup a cluster on Leap 15.5.
Host is a VM, followed instruction on SLE HA 15 SP4 | Installation and Setup Quick Start (suse.com)
When trying to initialize cluster (crm cluster init) on 1st node, the operation failed:
cluster.init: timed out
I do not find any relevant information in systemlog regarding the error.
All relevant services are installed (hosts file, chrony, ha-bootstrap, pacemaker, corosync) watchdog is configured, fencing device (SBD via iSCSI) is present.

Any help appreciated.
