Multiple Azure IoT Hub nodes refuse connection #35

Open janoschjg opened 5 years ago

janoschjg commented 5 years ago

Hi to all of you,

I have a node red instance which sends data via mqtt to several clouds simultaneously. Last week I've added a Azure IoT Hub node to it and as long as there is only one Azure node it is fine. But when I try to send data to different Azure endpoints, it seems like they are blocking each other so one always gets disconnected. I thought maybe the same messaging frequence could be the problem, which is why I time shifted the frequences of the messages. It worked for a couple of days but now one node is constantly disconnected (always the one I set up first)

Does anybody can tell me how you can make it work or what might be the issue?

Thanks in advance!

Following also. I have noticed the same observation - I have to change the protocol (HTTP->AMQL etc.) but then it still only runs for about 30hours~ before I need to repeat the process and redeploy the flow. I'm using both an Azure IoT Hub and IoT Central endpoint (which is just an IoT hub but buried under an abstraction layer). So, I'm not sure if it's the protocol being blocked when they are both configured for different protocols and still the same behaviour but maybe something else.
