Has anyone used server side epmautomate with a loopback (127.0.0.1) or "localhost" server name?

Summary: I'm using a groovy script that uses server side epmautomate. In place of the the server name in the URL, I would like to use a loopback address like "localhost" or "127.0.0.1". I can use a loopback in an EPM connection for making a REST call, so I know the server should be able to resolve the name. However, if I use a loopback with epmautomate, it fails. Has anyone found a way to make this work? It makes migrating code between environments much easier in the cases where I just want the job to run on the local environment
