I’m trying to follow this tutorial on connecting to AWS:
https://medium.com/accenture-the-dock/esp8266-aws-iot-core-guide-c640f2622a51
I’m getting the ESP8266 to connect to the internet but it seems like I can’t MQTT to subscribe. There is another forum post on this error that I’m getting but the solution to that post doesn’t work in this situation. Here is the error in the serial window:
