Cannot get MQTT server to connect to MQTT Explorer

I’m new to this, but after some trial and tribulation, I was able to get my RAK gateway and end-vice working on TTS V3. Now I’m trying to connect to the MQTT Server with MQTT Explorer, but can’t seem to get a connection.

I set up an MQTT Integration under Applications as follows:

  • Public address: nam1.cloud.thethings.network:1883
  • Username: mqtt-rpi3b@ttn
  • Password: (generated and copied API Key)

When I add those parameters to MQTT Explorer, I would expect to get a connection. But all I get is “Disconnected from Server”.

Hello. You get it working? I’m having same issue. Cant connect.

Thank you.

For MQTT connections you need the following.

Public TLS address - eu1.cloud.thethings.network (If you are using the EU1, otherwise the nam1 or au1)
Port : 8883
User name : XXXXXXX@ttn
Password : API key
Topic: v3/+/devices/+/up

All tis you get when you do the MQTT integration. MQTT Server | The Things Stack for LoRaWAN

Did you recorded this information when you did you MQTT integration and used it?
