Occasionally, when discovering tests on a device where a large number of tests are found, the web interface will time out and fail to configure tests.
The workaround is to discover such a device using network discovery.
* Delete the device if it already exists (this deletes all tests and history)
* Navigate to Administration --> Discovery --> New Network Discovery Session
For the Network scope, specify the device ip and a mask of 255.255.255.255, for e.g., 10.10.12.122/255.255.255
Set the discovery location as appropriate
Fill out he rest of the form and start the discovery
Once the device is presented, proceed with the workflow and discover tests on the device
The timeout will generally be handled here and the requisite tests discovered.
