Cannot Add Scheduling Service

PROBLEM

In the Manage Virtual Users dialog, the Add Scheduling Service button does not connect to a remote scheduling service.

Could not connect

SOLUTION

As of 2013.1.806, the Add Scheduling Service dialog only looks for Scheduling Servers that are listening on port 8009. If your scheduling service is listening on a different port, you will need to change it to 8009 before you can add it to the load test.
