by starting this
$mosquitto_sub -h eu.thethings.network -d -t '.../devices/../up'
he wrote this to me
âConnection Refused: not authorised.
I am recording and a pass a user
still gives me this
Your command line doesnât show that. What are you using as the user, and what as the password? (So: show us that youâve in fact read the documentation and tell us which documentation youâre using, rather than expecting people to list all possible problems.)
As an aside, '.../devices/.../up' is wrong too.
You need to provide an access token, similar to this:
mosquitto_sub -h eu.thethings.network -t '+/devices/+/events/activations' -u 'APP-ID' -P 'ACCESS-KEY' -v -p 1883
APP-ID is the actual name of your application.
ACCESS-KEY can be retrieved from the Overview page of your application (at the bottom)

in this option I write it
mosquitto_sub -h eu.thethings.network -t '+/devices/+/events/activations' -u '70...................81' -P 'AB.......................E3' -v -p 1883
and yet it gives me a mistake
Connection Refused: not authorised.
Connection Refused: not authorised.
I use this documentation from my site
https://www.thethingsnetwork.org/docs/applications/mqtt/quick-start.html
Read the manual again.
AppID == Application ID, that should be a short ânameâ, listed at the top of all information on the application page. It is not an EUI number.
AppKey should start with ttn-account-.

I think you are using appeui not the actual application name as your user. Also, check you are using the access key, starting with ttn-account
thank you all
it finally came about
he has been stirring all the time
-u "<AppID>" -P "<AppKey>"
Hello all,
I started playing with the Things Network recently.
I have successfully connected my device to the TTN and am able to see the packets being received by the TTN server on its application console.
However when trying to use MQTT (through mosquitto) on my laptop I am facing the same problem which @gandipg suffered.
On my laptop
I am entering the following cmd as mentioned in the Quick start tutorial
mosquitto_sub -h ev.thethings.network -t '+/devices/+/up' -u '2222' -P '...16 byte...' -v
I am getting Connection Refused: not authorised.
Now Mr @nicbkw mentioned that the access key starts with ttn-account.
On my application console my access-key doesnât seem to start with that anywhere.
Any clues as to where I am going wrong.
Your help would be appreciated.
Kind Regards
That doesnât look right. What region would ev be?
I just created a new application, and it still creates keys with that prefix. Maybe you can add a new key (for at least âmessagesâ) to fix that? If not, create a new application?
Also, itâs a lot longer than 16 bytes, for me itâs 58 characters.
Quick response as I am in the pubâŚ
If your application is called â2222â, then in the console open the overview for the application and it should look similar to this, just copy the key using the icon:
Thank you both for your quick response.
@nicbkw - thank you for suggestion for looking at the overview of the console. That resolved the issue.
My mistake was to be entering the App Session Key for the device I registered.
@arjanvanb - âevâ is a typo on my part when writing the question on this forum. I was using âeuâ as the region.
Regards
Hello,
when I try to connect with MQTT, getting âConnection Refused: not authorised.â but it was worked before. I am sure I use correct applikation Key, even I try to create new.
mosquitto_sub -h eu.thethings.network -t â+/devices/+/events/activationsâ -u â70B3D57ESKIPPEDâ -P âttn-account-v2.skippedâ -v
For the user you need to use the application ID (short text string).
Hello,
Yes. I use EUIS
Ed
Ok. thanks seems itâs working now with application ID.
but I remember itâs worked before with EUIS
