Not receiving data in application anymore, but I still see it in gateway tab

[Kvist]

Hi!

I am not getting any data in my application data tab in the ttn console, I see the data however when I look in the gateway data tab (its kept open the entire time)

Info:
handler: ttn-handler-eu
gateway: LorixOne
sensor: LoPy

Any idea whats wrong?

The system has been running smootly for months (~3-4).

Thanks.

Update: I am now recieving data in the application tab. It was unable to recieving any data for about ~30mins (20:20-20:50 CET)

Was there any problems on ttn’s side in this time period?

Seeing this issue too, even tried creating a new application and migrating devices over. Anyone have any troubleshooting tips?

Same problem here (US west). I was able to see OTAA activation but no futhur data package was received/displayed.

Which handler is used for the application (ttn-handler-eu for @Kvist) and which router for the gateway?

Like suggested in After successful OTAA, TTN Console shows uplink traffic in gateway, but no data in application:

@arjanvanb

Is the application also registered to a handler in the us-west region, like your gateway is?

@htdvisser

please make sure that your device is registered on a handler in the same region as the one your gateways are connected to. The transit traffic between regions isn’t always as reliable as we want.

And any chance you can use an MQTT client (or ttnctl subscribe ) to see if it the data is available even when it’s not shown in TTN Console?

Note that there has been some problems yesterday (20th Jan – eu handler):

(Times in CET)

My 4 gateways were receiving packets, but nothing on the application side.

@arjanvanb

Which handler is used for the application (ttn-handler-eu for @Kvist) and which router for the gateway?

ttn-router-eu for the gateway.

Its up and running again, as I mentioned earlier. No changes were made, and the gateway + application have been running successfully for several months.

Thank you for the info. By changing the handler I was able to get the data again.
Though I should have created a new application with the correct handler instead of modifying the old application. Because all registered device info will be lost if the handler is changed. I learned that too late.

[arjanvanb (Arjan)]

Didn’t you get a warning like the following?

Are you sure you want to change the handler registration for application <name>?

Confirm by typing the ID of the application:

All devices registered to this application will be lost

Having the same issue too. Tried to reset the device’s frame counter (ABP), but it didn’t help. Traffic shows up in the Gateway.
