OpenSSL wrapper is stuck and leading to connection time out

[Sourabh-ALTEN]

Describe the bug

I have an application developed using aws-iot sdk and it was working fine earlier. Now while connecting to aws the OpenSSL wrapper is stuck at ConnectTCPSocket:L271 But it says it could resolve the endpoint and after sometime it time outs. There was a similar issue https://github.com/aws/aws-iot-device-sdk-cpp/issues/5 but in my case network is available. Device is connected to network and also ping to aws endpoint is working.

Can anyone please let me know what could be the issue here and how to resolve it?

Which version of OpenSSL are you using? How often does this happen? Is it possible that your device is temporarily loosing connection?

[Sourabh-ALTEN]

Hello @jmklix , OpenSSL version on device is 1.1.1k. This is happening for the first time. I have tried with multiple network connections but it's the same situation. Is there any way I could check if this is related to dns resolving and network problem?

[jmklix]

Enabling the logs might let us figure out what is happening. You can do that with the following:

std::shared_ptr<awsiotsdk::util::Logging::ConsoleLogSystem> p_log_system =
    std::make_shared<awsiotsdk::util::Logging::ConsoleLogSystem>(awsiotsdk::util::Logging::LogLevel::Info);
awsiotsdk::util::Logging::InitializeAWSLogging(p_log_system);

[Sourabh-ALTEN]

Hello @jmklix logging is already enabled and the above code is already part of main()

You could try to reproduce it on a different device and network.

Nothing has changed with this sdk recently, so it probably isn't something caused by the sdk. Can you provide a minimal code sample and logs that reproduces your connection time out?
