MQTT Connection

Hi all
I have the following problem, my MQTT Broker cannot connect to TTN.
Do you see where my problem is?

MQTT_2

The port should be 1883.

For TLS port 8883 is used.

If you want to use TLS / port 8883 the following topic may provide some help:

Cannot connect to MQTT over the port 8883

It works with 1883.
Does anyone have experience with the Mosquitto broker?
I would like to subscribe the sensor data with the Mosquitto Broker.
is there a guide for that?

Thanks for your answer.
Unfortunately, I can’t do it with this manual.
Does anyone know of a simpler guide for windows?

fI’ve come a step further, but unfortunately not quite there yet.
I managed to get a message (subscried) from TTN with the following command.
Unfortunately, this still can’t be read into my system.
According to me, this message should now also be available on the Mosquitto for third-party systems, or am I seeing this incorrectly

Mosquitto_3

Please do not post images where text can be copied and pasted over.

In this case the text is laughable small - how do you think people can help if you post images like this?

According to you? What do you mean by this message should now be available for …

MQTT is like your postman, it doesn’t care what gets sent, it doesn’t know about what gets sent, it just sends what it’s given and you have to process it.
