I doubled ckeck my aws iot end point and it’s correct.I defined my device name in the aws client credentials.
That’s my policy
“Version”: “2012-10-17”,
“Statement”: [
“Effect”: “Allow”,
“Action”: “iot:Connect”,
“Resource”: “arn:aws:iot:eu-central-1:1860633:*"

“Effect”: “Allow”,
“Action”: “iot:Receive”,
“Resource”: “arn:aws:iot:eu-central-1:1860*****633:*”

Any help will be appreciated.This is not even the main project,this is to get along before the main project and time is not on my side again.

Hi Dan,

Thanks for your interest in amazon FreeRTOS!
As a quick look the Error number you received would be a socket timeout.
Can you confirm that you have a route to the server endpoint you are trying to access?
Can you confirm the server address you received from the DNS lookup is the one you actually want?
