Dear all,

i want to test

MQTT over TCP.

I've configured Message management Service cockpit, then I try to test connection using Messaging through MQTT over TCP. But in the screen the button "connect" is disabled.

Have you any hint?

Please note that MQTT websocket connection test works correctly.

Thank You.

    Hello Luigi,

    could you please double check if you have enabled "MQTT Connection" in the Configuration. See second screenshot in here [1] > point #2. Save your settings and try again.

    Also, it would be helpful if you check and share your browser console logs. Do you see any errors/warnings reported there? What browser are you using?

    Regards, Anton

    • Hi Anton,

      when I made the test the first time I used Chrome and with this browser I see the message:

      "The test client cannot connect to the MQTT broker endpoint."

      and the button Send was not activated.

      Then I changed browser and I used IE v.11 and with it I see the message:


      where is the IP address of MQTT broker but the button Send was always not activated.

      The problem is the same i.e. it is not possible sending messages to MQTT broker because it is disconnected.

      How does SCP check if MQTT broker is connected or reachable?

      Thank you for responses to my answers.

      Bye Luigi
