We recently setup a PRTG Failover Cluster node and everything connected and setup fine. We have been getting an error regularly overnight where the Cluster node will show up as the Cluster Probe device being disconnected for a short period of time and then re-establish. We have been unable to find any cause for this and was wondering if anyone else experienced this and may have found a reason. Windows logs and PRTG logs do not seem to show any reason.

Hello,

Please forward us also a Support Bundle from both cluster nodes for analysis. This can be done via the "Contact Support" ribbon in the lower right corner of the failover´s web interface. Please refer to this kb post.

?? What was the result of this?? I'm having a similar issue. many times a day my cluster health sensor goes down. Indicating the same error "Cluster nodes Disconnected".

In that case the issue was that the Failover occasionally lost connection due to network problems. Please check the connection between the two nodes.
