I am aware of, if If the node wants to join a cluster and the cluster access key is correct then it connects to the master, and then the master will update the failover with the current PRTG version. But not sure, why it is not happening for me. These two servers are assigned with public IPs and communicating over the internet and not in a LAN network. Everytime I get this message- Cluster: Access denied for node at A.B.C.D:49168 (Incorrect software version).
Cluster: Access denied for node at A.B.C.D:49168 (Incorrect software version)?
