Maqueen Lite Not Working with the Gamepad

Hello,

I'm trying to get my Maqueen Lite with the forklift to be able to be controlled using the DFRobot gamepads.

I used this tutorial from DFRobot educational forum. https://edu.dfrobot.com/makelog-308487.html

The sample code I'm trying to use is as follows https://makecode.microbit.org/_CkVduYFjHhjX 

This code used to work for me in the past, but now it says “The hex file is not available, please connect to the internet” even though I'm clearly connected to the internet.  (See the screenshot below) 

I'm not sure what's wrong, but if anyone has working code to use the gamepad with any of the mechanic components or any insights, I'd greatly appreciate it.
