Can't connect to network-server my P-NUCLEO-LRWAN2 on chirpstack

Hi, I got a problem, I can’t connect to the network server my gateway P-NUCLEO-LRWAN2. There is very little documentation on the web for this gateway so that’s why I create this topic maybe some people could help me.
I have my computer with Linux and the gateway-bridge, the network-server, and the application-server run on it.
My gateway is connected to the internet with the ethernet port of my computer.
I enter the EUI of my gateway on the Chirpstack application and I see that :

I took a look at some of the logs and the error seem to be with the network-server.

Chirpstack-network-server[50078]: time=“2020-09-22T17:40:03+02:00” level=error msg=“uplink: processing uplink frame error” ctx_id=f510b570-2ec3-47a7-ae5e-c3402fe8f80a error=“get device error: object does not exist”
Chirpstack-network-server[50078]: time=“2020-09-22T17:40:06+02:00” level=info msg=“finished unary call with code OK” ctx_id=f83faf39-2374-48b9-9e16-45d4f4f

At first, I thought I made a mistake with the EUI of the GW but it seems to be correct at least so I really don’t have a clue about this error.

Could anyone help me, please?

More interesting now the gateway and the node seem to be active and send data actually but the application server continues to show that the gateway is inactive weird.
The screen of my dashboard:

But there still is this error in the network-server journal:

Does anyone have an idea?

create device in chirpstack.

Hi, @eugenev thanks for your response ! sorry at first because I’m new in LoRa stuff but what do you mean by creating a device? Like creating a device profile for the Gateway?

thanks

I mean create device in chirpstack app-server

I’ve already created a device for my node and I am able to get datas from it on cayenne dashboard. Should I create a device for the Gateway ?

device is device
gateway is gateway

read the docs on main site

Ok I see
So why I have to create a device if a device is already created for my node in order to fix my problem?

error: object does not exist - this means that your gateway receiving packets from device which not added/joined into chirpstack. that’s all.
Why are you sure that these packets from your device and not from another one?
goto to the gateway live frames tab and inspect traffic.

Maybe I was not precise enough but my big issue is that I registered a gateway LoRa I’m able to see data send to the network server with the live Lora frame utility and the journal but on the app I can’t see the activity of this gateway. I just have one gateway and one node so it’s weird

mybe you are not properly create the gateway in chirpstack.
