Connected to wss but MQTT connect fail

[kami90]

I can connect to wss, but when mqtt is connecting, I receive msg "WS-Client: connection lost". What is my problem?

What arduino IDE and ESP core are you using?

[kami90]

i have used arduino 1.6.8 version and esp8266 library 2.3.0

[tommakov]

I appear to be having this same problem. Any solution? ( I'm using arduino 1.6.12, but don't know where to check the "ESP core". ) Any help would greatly be appreciated!

[tommakov]

I'm also using "esp8266 library 2.3.0" and the "Dependancies" from a few days ago.

I have same problem. anyone know how to solve the issue yet?

[knownothing8]

Look like it is AWS IAM policy needs to be set accordingly for user or group to have proper access permission right:

Go to https://console.aws.amazon.com/ Then click IAM Then click policy. find your policy or create a new policy
set service to IOT set action to iot:* set resouce to all resources (I have difficulty to know how to set specific resource. So I just set it all for the experiment)

After, I was able to get MQTT connected!!!

I signed up to thank you knownothing8! As soon as I changed the policy in IAM, I am now able to connect MQTT! You saved my time, hwah, Great Respect.

@jill6 @knownothing8 updated readme with this step-by-step procedure to grant iot permission for the user. thank you
