MagicMirror AVS Sample App Client Problem

Hi there,

I have a problem with the client. I using the AVS on my magic mirror. After upgrading the rasbian the AVS doesnt work anymore. I am not really good in programming and everything. There are 3 Steps, after installing everything. See below. The Output is also below. Hope you can help me. Nearly everything worked and I was ready to build a MagicMirror Frame and now Alexa AVS is not working anymore.

Run your web service, sample app and wake word engine

Now that installation is complete, you’ll need to run three commands in 3 separate terminal windows:

Terminal Window 1: to run the web service for authorization (Is still working)

Terminal Window 2: to run the sample app to communicate with AVS (is not working)

Terminal Window 3: to run the wake word engine which allows you to start an interaction using the phrase “Alexa”

This question seems very specific to MagicMirror, which I’m not sure a lot of people on this forum have experience with. Have you tried posting over at the MagicMirror Forum?
