ThinkNode G3 already registred

Hi, I’m new and just purchased a gateway (ThinkNode G3). I tried to register it, but it says that “a gateway with EUI…… is alrady registred by…”

I’ve searched other posts but haven’t found a solution.

the error detail is

{
  "code": 6,
  "message": "error:pkg/identityserver:gateway_eui_taken (a gateway with EUI `CCBA97FFFE18889D` is already registered (by you or someone else) as `eui-ccba97fffe18889d`)",
  "details": [
    {
      "@type": "type.googleapis.com/ttn.lorawan.v3.ErrorDetails",
      "namespace": "pkg/identityserver",
      "name": "gateway_eui_taken",
      "message_format": "a gateway with EUI `{gateway_eui}` is already registered (by you or someone else) as `{gateway_id}`",
      "attributes": {
        "administrative_contact": "serlli76",
        "gateway_eui": "CCBA97FFFE18889D",
        "gateway_id": "eui-ccba97fffe18889d"
      },
      "correlation_id": "80b75dcd69cf4199ba40b26f9d53750b",
      "code": 6
    }
  ]
}

What can I do?

Thanks for your help.

This means the ThinkNode has already been used on TTN.

However, as it is a Single Channel Packet Forwarder which is no longer supported, the EUI being taken is a secondary issue.

You need to purchase a gateway which can listen on 8 channels at the same time, not just one.
