Duplicate node ID



I had a PRTG cluster with a master and a failover. For various resons I wanted to swap their roles. For that I made both stand-alone and then created the new cluster on the new master node. On the failover node I said to join the cluster. This doesn't work however and I notice that both servers have the same node ID's which doesn't seem right.

I'm running the latest version 9.1.4

Dear Jeffrey,

please try shutting down both nodes. Then completely uninstall PRTG from the failover-node and also make sure that all registry-settings are removed and gone (see How and where does PRTG store its data? for details). Then restart the master node and please install PRTG anew on the failover-node and do join the PRTG cluster anew.

best regards.
