I fail to run the sample basic-connect.
i receive:

Connection failed
[...]basic_connect\build\x64-Debug\basic-connect.exe (process 30292) exited with code -1.
Why is there an overflow ("-1073741252")? I identified 1049 to be "AWS_IO_SOCKET_NO_ROUTE_TO_HOST", what does that mean?
Why is the connection not successful?
I am using msbuild & win10.

I am not so sure. It worked to
ping [...]-ats.iot.eu-west-1.amazonaws.com. A colleague of mine managed to establish a mqtt connection on this very endpoint from the same network as mine.What is different between your setup and your colleague's?
This GitHub issue maybe helps: https://github.com/aws/aws-iot-device-sdk-cpp-v2/issues/440 . The reporter doesn't mention the error codes you've got, only the hangup. In that case, it's a problem with the IoT policy. Please check the IoT policy attached to the certificate of your Thing. I would not expect you to get network unreachable because of a policy problem, but policy problems are a common cause of connection issues.
Yes, sry. I forgot to mention that. I think the main difference is the way we generate the certificate.
We use JITP and i just realized that the clientID should be the common-name of our certificate according to our policy. So now i manage to reach
print("Connected!"). However, I still receive STATUS_NETWORK_UNREACHABLE & AWS_IO_SOCKET_NO_ROUTE_TO_HOST errors. Especially, everytime i try to subscribe. I can try to run basic connect with my cert on another machine.
