QRadar: Custom Action Script cannot resolve Host Name when fired from a Managed Host

Troubleshooting

Problem

In QRadar, The Custom Action Script fails when the script references a external host name.

Symptom

The Custom Action Script works correctly when:
• The Event that triggers the Rule that fires the Custom Action is received on the QRadar Console.
OR
• The Script that is being used by the Custom Action is attempting to communicate to an IP address instead of the Host Name.

The Custom Action Script Fails when both of the following are true:
• The Event that triggers the Rule that fires the Custom Action is received on a QRadar Managed Host.
AND
• The Script being used by the Custom Action is attempting to communicate to a Host Name.
