Hi all, I've build a NODE-RED flow with the following nodes: 1 node type INJECT 1 node type MQTT_OUT connected to SCP Cloud Platform IoT with TLS v1.2 1 none type MQTT_IN connected to SCP Cloud Platform IoT with TLS v1.2 1 node type DEBUG The node INJECT sends a message with body JSON to node…

Well I just installed mosquitto and ran your flow with no changes and it works fine. I'd suspect the node.js version. You might want to downgrade

Hi Afelix, I've inserted backticks between the json flow.

I hope the forum software didn't eat any of the characters like it does when editing like this... Going to see if I can see how you set up your debug nodes, will reply in a minute. Okay what I can see now which I couldn't from the original way you posted the flow is that you only have exported the …

Hi Afelix. Sorry, now I've copied the whole node-red flow. Please chek again. It looks like the no message is received by node MQTT_IN even though the message is sent from node MQTT_OUT to SCP IoT. Thank you.

There are MQTT clients for iOS and Android have you tried connecting one of those to your broker to ensure that they can receive something?

Hi Luigi, I just tested your flow, setting the connection to my own local broker. Works exactly as it should. Have you tested the connection itself to your broker without node-red? For example by using a tool like MQTT Explorer? MQTT Explorer v0.2.0 - MQTT swiss-army-knife Setting up a connection…

Hi Afelix, yes I've a folder named Desktop on my desktop so the path should be correct. I notice that if the nodes MQTT are configured on localhost both with 1883 the scenario works. The MQTT_IN node listens on port 1883 while MQTT_OUT publish on the same port. The problem rises when the nodes M…

Hi @mirou_IoT , I believe it would be better if you created a new topic for your issue. I can’t see how it is related to MQTT nodes with tls v1.2 not passing through messages.

[image] alboino: In this case MQTT_IN should listen on port 8883 and MQTT_OUT publishes on the same port but the flow does not work. I see that MQTT_OUT publishes the message on port 8883 but MQTT_IN does not catch it. Different approach trying to figure out what's going on. Seeing how this …

[image] alboino: In this case MQTT_IN should listen on port 8883 and MQTT_OUT publishes on the same port but the flow does not work. I see that MQTT_OUT publishes the message on port 8883 but MQTT_IN does not catch it. If you tried defining a MQTT-IN to listen on port 8883?
