Hi
I had an environment of webMethods 7.1.1 in which I had configured and deployed the analytical engine, the prediction engine and data collector engine.
But after upgrading to 712, as per the upgrade documentation, I created a new environment but the deployment fails for analytic engine with the below errors (followed by the deployment success of data collector and prediction engine):

Error deploying logical server type “Analytic Engine v7.1.2.0” version “7.1.2.0” to host “”
Deployment Error: java.rmi.ConnectException: url = https://:15000/services/IRemoteConfiguration
One or more of the following configurations could not be deployed

What could’ve gone wrong with the upgrade for just the Analytic engine failing to deploy?

try setting your port number to 12503 and then try deploying
