Console-to-Engine Communication Failed (AzureVM Scan Engine)

Hey everyone,

I spawned a AzureVM according
Azure Scan Engines | InsightVM Documentation (
and want to use the Standard Console to Engine sync.

Does someone have an idea, why I’m getting this error?

After the failed sync, also no console.xml is created at the AzureUbuntuRapid7VM.


were you able to resolve this ? I have set up the azure scan engine with inbound rules using gateway address for my scan console (my scan console has a 10.x.x.x address). I do see a traffic allowed entry when I try to define my scan engine in the admin page of the Security console. But the consoles.xml does not get created in my azure scan engine and I get a in the nsc.log

Has someone found the solution to this issue please ???

The java error basically means there’s still a connection issue e.g. something blocking the traffic. I would do a traceroute from the console to the engine to see what all hops it needs to take to get to that scan engine and find out where the traffic is being dropped. It could be the local firewall on the scan engine, any firewall between, or something in Azure not letting the traffic out.
