After deploying the cluster probe, we see it failing to connect to secondary nodes with this error:
In this case, the issue was being caused by a timeout with the network connection between the two nodes.
UIM version 8.51
cluster probe version 3.50
**This information is generally applicable to all versions of UIM / Cluster probe
Raise the communication_timeout value within the probe configuration to allow the probe additional time to make the connection.
