AWS_IO_TLS_ERROR_NEGOTIATION_FAILURE on 1.0.6 (awscrt 0.5.13)

I’ve searched for previous similar issues and didn’t find any solution

Describe the bug After upgrading my installation to awsiotsdk-1.0.6 it stopped working with awscrt failing to authorize with aws’ backend. Might be connected with awscrt upgrade to 0.5.13.

SDK version number awsiotsdk-1.0.6

Platform/OS/Device rpi3b+

To Reproduce (observed behavior) Upgrade awsiotsdk to version 1.0.6.

Expected behavior Should work as expected.

@JonathanHenson I was using the old endpoint (<endpoint-id>.iot.us-east-1.amazonaws.com), I switched to the ATS one (<endpoint-id>-ats.iot.us-east-1.amazonaws.com) and now it works. Thanks for your help!

Thank you Mario for sharing the link to that post here. Again: https://aws.amazon.com/blogs/iot/aws-iot-core-ats-endpoints/

The default configuration for V2 device SDKs will no longer work with the old non-ATS endpoints. Run aws --region <region> iot describe-endpoint --endpoint-type "iot:Data-ATS" to get the ATS endpoint.
