Due to a migration to a different datacenter, I want to add an additional host to the cluster. It's connected via site2site VPN, but in another subnet.

Firewall is opened, the hosts can ping, ssh, etc. each other. Unfortunately adding the host hangs at "waiting for quorum..." - I waited for a whole night by now. Is there any multicast or other subnet-internal technology involved that might be an issue? Is there a way to fix?

root@host3:~# pvecm add 10.0.1.11 -link0 10.0.2.2
Please enter superuser (root) password for '10.0.1.11': *************
Establishing API connection with host '10.0.1.11'
The authenticity of host '10.0.1.11' can't be established.
X509 SHA256 key fingerprint is 35:7D:4D:A7:C6:02:1C:4C:32:57:A3:1D:64:4B:57:9F:59:E2:8A:02:33:3D:4D:BD:1B:1F:3F:A9:E6:7A:23:F7.
Are you sure you want to continue connecting (yes/no)? yes
Enter totp code for user root@pam: 228874
Login succeeded.
check cluster join API version
Request addition of this node
Join request OK, finishing setup locally
stopping pve-cluster service
backup old database to '/var/lib/pve-cluster/backup/config-1758412376.sql.gz'
waiting for quorum...

One new Host: 9.0.3, Two old Hosts: 8.3.4

Adding via CLI due to TOTP on the old hosts - if that would help, I could also switch it off to add the host

This is actually solved, the issue was that the actual link of the other two hosts was a dedicated network that wasn't reachable for node 3. I added additional links to the corosync.conf of the existing cluster, afterwards it worked
