As far i understood, PRTG cluster has no possibility of connecting to PRTG webserver using a virtual IP (VIP). When a PRTG master node fails, all clients and smartphones need to manually connect to the slave node.
I would like to have ONE VIP where clients connecting to and then automatically failover to the slave node. I tried to achieve this using Microsoft Windows Failover Cluster, just configuring an "entry-point" VIP which seems to work on the master node.
During testing I have configured the webserver on the master node to listen to the VIP in addition to the primary IP address. The problem: When failing over the VIP to the slave node, I get a ERR_CONNECTION_REFUSED from slave node when connecting to the VIP. Because the PRTG configuration is fetched from PRTG master node, the webserver on the slave node doesn't listen to the VIP anymore (because it's not present on the master node at this time).
Is there a "hack" to force PRTG webserver to always listen to the VIP although the IP address is not present?
