enabling scripting on server

I am trying to enable to run scripts on the server. I see in the documentation that the gateway is not set up by default.

When I use Tools>Server Console, I can see my gateway enabled, though there is no specific listing for scripting. However, I am able to submit jobs such as Discover jobs, etc.

However, I am unable to submit script jobs to the server. When I use Tools>Scripting>Script Job..., the dropdown for Gateway location is grayed out even though the server is listed using 'Tools>Server Console'. Is there a server application for scripting that is perhaps not installed? I can't figure out what I can't set the gateway for scripting submission.
