[PVE-User] problem with cluster configuration, please help

[Жюль Верн]

Good day ! I install three nodes of proxmox from image. And try to create a
cluster. Command pvecm create proxtest on node1 was successful, type pvecm
add on node2:

root at pve:~# pvecm add 10.22.16.50
The authenticity of host '10.22.16.50 (10.22.16.50)' can't be established.
ECDSA key fingerprint is 1c:e8:06:20:76:4d:a0:89:f1:22:92:81:1f:af:b2:1b.
Are you sure you want to continue connecting (yes/no)? yes
root at 10.22.16.50's password:
node pve already defined
copy corosync auth key
stopping pve-cluster service
Stopping pve cluster filesystem: pve-cluster.

At this moment i type pvecm add ... command on node3 and get "unable to
copy ssh ID" What i doing wrong ?
