We are getting below error when adding a second cluster node
Upgrade failed after 2 seconds.
Exit code: 3
IP address <IP-1> used in previous installation doesn't belong to this machine anymore.
Just to highlight that <IP-1> is the IP address of the first Cluster node
Solved! Go to Solution.
So you either had a problem when uninstalling the previous attempt to install Dynatrace Managed on this host and /etc/dynatrace.conf was left - for example, you might have cloned the machine from the first node. Or you're passing in the installation parameters the IP that's not on the host's interfaces list.
