I set up a subscription connection to the mqtt broker for a public channel that I've already added my device to. I'm confident that all of my username, password, client_id, and topic configurations have been set correctly. When I connect using MQTTX or mosquitto_sub, I don't receive any data. It says that my connection is successful, but proceeds to sit endlessly with no data being received. I'm at a dead end here. Does anyone know what I could be doing wrong?

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

Hi :-) I have followed the instructions on mathworks site: https://se.mathworks.com/help/thingspeak/use-desktop-mqtt-client-to-publish-to-a-channel.html I have downloaded the MQTT X software. Then I add a new connection as described. The username, password and ID i get from my thingspeak device in my account. I then at 3) "Click" the connect button, the program replies "connected". But within 3-6 secounds the connection is lost... so I never get to test out the rest of the subscription and publish. This should not be a difficult task, but I an stuck :-( Are there anyone experiensing the same? mvh vegar bartnes
