Hi,
I've got an issue similar to https://community.cypress.com/thread/52154?q=aws%20iot AaMo_3399246 . The issue was locked, but it was not resolved.
I'm using AWS MQTT demo on CY8PROTO-062-4343W PSoC 6 Amazon FreeRTOS (git clone --recurse-submodules https://github.com/cypresssemiconductorco/amazon-freertos.git --branch 201910-MTBAFR1951) and getting MQTT connection timeout error while connecting to AWS IoT Core. I've increased timeout to 60 seconds (in iot_demo_mqtt,c set MQTT_TIMEOUT_MS to 60000 from 5000) and still getting the same error. I'm using ModusToolbox IDE on Ubuntu 18.04 LTE to build/deploy this demo.
Here is the log:

Both of them have the same policy to access AWS IoT Core. I think the issue may be related to clientId/cert/key.
I've got the same error when I used cert/key pair using basicPubSub.py demo code.

But the same basicPubSub.py demo code works fine with another provided key/cert.

I've resolved the issue. Somehow I haven't activated the certificate attached to my thing. I've activated it from IoT console (Thing->Security->Certificate->Actions->Activate) and all start working.
I'm wondering if AaMo_3399246 had the same solution.
