No Key

[dr-apple]

I have all make but i dosen't become a the key:

Ask your Echo "Alexa ask kodi for my key" (Your Key will be sent to your alexa app.)

and alexa say:

The remote endpoint could not be called, or the response it returned was invalid.

What is the Problem ? In Kodi i have all install and the Kodi Plugin (0.1.2) call for the key !
