I looked into the .NET code of the extension, and found that it does not define the property value of System.Net.Requests: public bool UsePassive.

Per the .NET docs for System.Net.Requests.dll - if that value is not set, passive defaults to true.
You should be able to modify the C# extension for your own needs if you desire it to be active.

Ideally you would modify it to use an input variable to give the option to choose rather or not to use active or passive.


Hope this helps.
