Are you already running a Codesters project in another tab or window?
Micro:bit can only connect to one web page at a time.
Try stopping other Codesters projects or closing
other tabs or windows that may be using your Micro:bit.
If that doesn't fix the problem try disconnecting your Micro:bit,
reloading this page, and reconnecting your Micro:bit.
