App not located in dropdown - Writeback Server Destination setup

We have recently installed the Writeback Server and are testing the setup.  I am trying to create a Destination with SQL s the type. However when I get to the step "Add the writeback App you want to use.", I do not see the app I created for testing. I see other unrelated apps.

Is there a step I am missing? Do I need to refresh some type of connection?
