Why does node B refuse to join cluster on node A?
Both nodes are on the same LAN
Node b is empty (no vm)
The only thing between the 2 nodes is an hpe switch with IGMP snooping and querier enabled.
There is a pfsense box between isp and proxmox so it should not interfere with cluster.
Proxmox firewall is off, yet udp ports 5404-5412 seem to be closed.

thanks Chris,
Correct, empty node B (192.168.55.115) is failing to join already existing cluster node A (192.168.55.114).

here is the output message:
Establishing API connection with host '192.168.55.114' Login succeeded. check cluster join API version No cluster network links passed explicitly, fallback to local node IP '192.168.55.115' Request addition of this node An error occurred on the cluster node: can't add existing node 'pve' TASK ERROR: Cluster join aborted!
