Make sure the username and password that you put in the driver is correct. Another common reason is the player name doesn’t match what was specified. Make sure the player name that you specified in the driver is spelled exactly (case-sensitive) as the name that was set in the Blackdove phone/tablet app. If you need to update, make sure you reboot the UI and the CH processor (so that the latest settings are loaded). If you have done this and still have no control, check to see if you can control the player in the Blackdove phone/tablet app. If you can not, than remove the device and re-pair. Once you confirm the player can be controlled with the Blackdove phone/tablet app, check the player name and reboot the processor and UI. If you’re still not able to control the player through the official Blackdove app on your phone/tablet, then contact Blackdove for further support.
