Solution

Your VM does not seem to have the data network enabled, so MARS cannot reach the server. At this point you have 2 options:

Provision a new VM instance

Follow the steps in Provision a new instance - web to provision a new Virtual Machine, taking care of enabling the data network besides public or private.

Reconfigure the existing instance

1. In the web portal, go to Provision - Instances and click on the instance you want to fix.
2. Click on the ACTIONS button on the upper-right side, and select Reconfigure from the drop-down menu.
3. Add the missing data network from the list of networks, after public or private.
