I know I am not the first to ask this question but to date have not found an acceptable answer. When I try to download an application to my EV3 I get the following response:

The following error occurred during deployment to your hardware board: Failed to download application to EV3: Cannot connect to EV3 brick through WiFi. Make sure: 1)EV3 is connected properly through WiFi and the Device ID along with the IP address entered in the Configuration parameters matches the device ID and IP address of the Brick. 2)No connection to the EV3 brick is established through EV3I/O. Clear any existing EV3I/O object.

I have used !ping to verify communication between my surface and the brick. I have also cleared any existing EV3I/O objects from the command window, workspace and command history. I have also verifed the brick IP and name and made sure my brink has the current firmware application installed (V 1.10E). In the past I have successfully downloaded applications on other bricks using the same meathods. Is there something I am missing?
