Can not connect to ThingSpeak MQTT broker using MQTT X Client

54 views (last 30 days)
Hello,
I have a problem with the connection to thingspeak MQTT broker using MQTT x client. After pressing the "Connect" button after a few seconds connection is not set.
I have followed the instructions described in: https://de.mathworks.com/help/thingspeak/use-desktop-mqtt-client-to-publish-to-a-channel.html.
Below you can see the settings in the MQTT X client. ClientID, Username and Password I took from the credentials file which was created when I add a new MQTT device in thingspeak.
I have already checked the discussion with a similar problem, but I can not figure out what could be the source of the problem.
I would like to ask your help with this problem.
Thank you,
Levani Meskhiya

If you're connecting over Secure MQTT, you need to use port 8883, not port 1883 as your screenshot shows.
