Subject: [paho-dev] Paho C Client ssl connection with Azure
Date: Thu, Jun 2, 2016 1:29 PM
 

Hi,

 

I am trying to connect to Azure IoT Hub using MQTT with Paho C client library. I have installed Paho GUI client also in my PC for testing purpose.

 

Establishing a connection to Azure is explained in the below link.

https://azure.microsoft.com/en-in/documentation/articles/iot-hub-mqtt-support/

 

IoT hub connection needs only the below parameters:

URL                                                        :               ssl://xxxxxxxxx.azure-devices.net:8883               

Clean Session                                    :               Enable

Username                                           :               {iothubhostname}/{device_id}                                  (Ex: xxxxxxxxx.azure-devices.net/device0eac6f2a40ef48c89abc10b9be0b9909)

Password                                            :               SAS Token from Azure

 

If I try connecting with Paho GUI App, it’s getting connected to Azure.

But if I try with my C client I’m getting an error message in the log as below.

 

20160602 151321.135 getaddrinfo failed for addr ssl:// xxxxxxxxx.azure-devices.net with rc -2

20160602 151321.135 ssl:// xxxxxxxxx.azure-devices.net is not a valid IP address

20160602 151321.135 getaddrinfo failed for addr ssl:// xxxxxxxxx.azure-devices.net with rc -2

20160602 151322.857 ssl:// xxxxxxxxx.azure-devices.net is not a valid IP address

Failed to connect, return code -1

 

Please help me to resolve this issue.

 

Thanks & Regards,

Manoj Srinivasan R.

I have masked the actual IoT hub name in my mail. If you are really needed that to solve the issue, I can share the actual host name and credentials.

The host name is correct and I have verified its connectivity by paho GUI client app. Only my C client is not able to connect to the host.

 

Thanks

Manoj.

Looks like the host xxxxxxxxx.azure-devices.net doesn't exist. Not sure whether you've obfuscated it from the mailing list or if that's what's in your code, but either way you will want to check that you're using the correct hostname.

Kind regards,
