Dears,
I have an issue to connect to tnt with node red “tnt uplink” (or ttn event or ttn uplink)

ttn Gatway receive the data from lorawan device
Data are available in the application
I can send the data by integration and retrieve with “Mqtt in”

But “tnt uplink” never connect the best i have is “connecting”
I suppose is related to ID/Key access (I red all I can found on the subject like : https://github.com/TheThingsNetwork/nodered-app-node/blob/HEAD/docs/quickstart.md ).

I red and applied all I can found on the subject like :

github.com

TheThingsNetwork/nodered-app-node/blob/HEAD/docs/quickstart.md

## Quickstart

This quickstart will walk you trough the usage of the TTN node-red nodes for
listening to device uplinks and events, as well as sending downlink in response.

### Setting up the environment

1.  Make sure you have [Node.js](https://nodejs.org/) installed.
2.  Install Node-RED using `npm`:

    ```bash
    npm install node-red -g
    ```

    See Node-RED's [Getting Started / Installation](http://nodered.org/docs/getting-started/installation) for details.
3.  Install the TTN Node-RED nodes:

    ```bash
    cd $HOME/.node-red
    npm install node-red-contrib-ttn

I have three Access key Default, app, home (link to the captor configuration)

Any help appreciate

Just use the standard MQTT nodes for connection to TTN v3 as this is the preferred method - there is a guide and lots of info on this forum (search mqtt ttn v3), as for node-red-contrib-ttn (node) - Node-RED it is NOT supported anymore so please don’t use it.
