I setup a user and have the counter id in. I see packets going out to the gmc IP (not analyzed them yet). If I run the "Test connection" it just sits there for awhile and then disappears. No message about failing etc. To date I still see nothing on the map nor when I look at data in Manage Devices.
Ok I am an idiot. When looking at managed devices I thought it had already created a counter ID for me when I first registered hence was using "404" for the counter ID. I just added a device and selected the map area again and presto. Now Test Connection comes back with "SUCCESSFUL".
