- Wed Dec 06, 2017 9:43 am #72339 make sure that AWS IoT is set up correctly and the credentials are all correct.
checking via AWS IoT Test Client will do.

I tried to use the credentials you posted (not sure if you really posted it correctly though), but I was not able to connect to WS server. mine is connecting just fine.

How is this an ESP8266 question? Ask in an AWS forum.

Since it is running on esp8266 platform
