Esp8266 mit Fire TV Cube (2. Generation) Discovery Issues

[MoinMeister3]

Hello,

I Have the Issue that My Fire TV cube can't find My ESP8266.
I'm using the Fauxmo 3.4.0 And the ESP8266 ESP 12F.
I Tyed it with the Fauxmo basic code and The ESP is detectet in my Network.
They are in the same Network and are allowed to talk to each other.
Allthough i tryed to restart the alexa.

Thanks for Helping
