Or buy a TTIG - once I got the client to do that, all was revealed. ---

We can’t switch to a different gateway now, we’re starting a traning tomorrow involving this gateway ☹ We can move it one day later but not much more I checked the gateway configuration and I don’t see room for errors. **Service provide** r: TTN V3 **Server Address** : eu1.cloud.thethings.network **Up/Downlink port** : 1700 **Secondary Server:** Disabled **Frequency Plan** : EU868 (Im in Spain) And the UID has already been recognized by the server What else can I check?? ---

Nothing, if two different makes of device aren’t getting the join accept and as I’ve had the same problem in the last few weeks with a Dragino gateway which was instantly solved when a TTIG was substituted for it, then just buy another gateway from a next day distributor. ---

Gotcha,so we will call this one faulty and get a new one. Unortunately the amazon link at the TTIG website is only for DE, and here in Spain a quick search for the device didn’t show any products, but we will keep checking! Thanks ---

It doesn’t have to be a TTIG - any LoRaWAN gateway from anywhere will do. It’s just a TTIG is cheap enough to have lying around as a backup plan. ---

Ok anyway we finally found a provider for this that can ship it. It will take some 5-10 days but we realized we just received another gateway (RAK) so we¡'re going to set this one up asap Thanks! ---

Final note on this. We installed another gateway (RAK) and everything worked right away so definitely the dragino was the culprit. Thanks everyone! [Previous page](https://www.thethingsnetwork.org/forum/t/elsys-co2-stuck-in-join-accept-loop/59146.md?page=1)
