When attempting to run a load test, the test list fails. The test list results for the load test contain this error: "Cannot Dispatch Load Test."
This error can occur when a firewall is blocking the port that the load test requires. The more load tests you run, the more open ports your Execution Server may require. To resolve this behavior:
Ensure that any active firewall on the Execution Server(s) running the load test is not blocking the ports in the range 8030-8039.
If this does not resolve the behavior, try unblocking a larger range of ports in the range above 8039 (for example, ports 8039-8059).
If the behavior still occurs, try closing and re-opening the Test Studio Test Runner System Tray process.
