Connection issue with node-red-contrib-ttn,ttn uplink

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 ).
