Ceph rados_connect failed

This happened when creating a new cluster with the 5.3 ISO.

I created 3 PVE VM's for testing, created a cluster with the nodes and installed pveceph on all 3 nodes.
After running "pveceph init --network" and "pveceph createmon" on the first node the other nodes can't connect to the monitor.
This results in the nodes not being able to display the Ceph status, cursh map, create OSD's, etc and showing a
rados_connect failed error.
In my case a temporary solution is to simply create a monitor on all nodes, but I would expect this to work out of the box.

Did I do something wrong or is there a bug in the creation of the Ceph cluster?

you must have a monitor or an OSD on a node to see the status.
If you have no OSD or MON on the node and want to see the overview you have like the ceph.conf in the /etc/ceph/ dir.
