Setup failed! -1 - Error code MQTT over Websocket configuration

[raftalarico]

Hi there, I'm trying to set up the Alexa-Arduino Christmas tree project you see here: https://github.com/KayLerch/alexa-xmas-tree

But after uploading the following arduino sketch to the Arduino Yun, I keep getting the "Setup Failed! -1" Error.

Tried Telnet and connection is ok, but probably some issue with authentication. I've checked the pem certificate is in the right folder: /root /AWS-IoT-Python-Runtim /certs aws_iot_root_cert_xmastree.pem

*please note that I'm using MQTT over Websockets connection.

Thanks in advance for your help!

I've added the debug line Serial.println(rw_buf); to aws_iot_mqtt.cpp

and this is what I'm getting: `
