Orphaned Device from Deleted Application - Unable to Re-register

End Devices (Nodes) Hardware
1

Hello,

I’m experiencing an issue with orphaned devices from a deleted application blocking new device registrations.

Situation:

  • Deleted application: ct74e3bbe8641245889a57cbc6c1d15f2b

  • Orphaned device still registered in the system:

    • Device ID: device-1774410442638

    • DevEUI: 2C F7 F1 C0 73 30 AA 09

    • JoinEUI: 69 D2 8C 8A 67 41 53 78

Problem:
When trying to register new devices (SenseCAP LoRaWAN sensors) in a new application, I receive this error:
“An end device with JoinEUI 69D28C8A67415378 and DevEUI 2CF7F1C07330AA09 is already registered as device-1774410442638 in application ct74e3bbe8641245889a57cbc6c1d15f2b”

The issue is that the application has been deleted, so:

  • I cannot access it via the Console (no rights)

  • I cannot delete the device via API (returns “no rights for application”)

  • The device identifiers remain locked and block any re-registration

Thank you for your assistance.

Best regards,

it seems that all devices bound to an application doesnt get deleted when the application is.

this is what i call a BUG.

maybe there is a dialog missing to transfer the devices before the application gets deleted OR that the deletion of an application is blocked as long as there are still devices bound to it.

you are better off to contact the support. they should be able to delete the devices from the databases.

Feel free to log an issue on GitHub.

Solved by forcing a new JoinEUI in the device.

Hello TTN Team,

I am the previous owner of the TTN gateway:

  • Gateway ID: lech01

  • Gateway EUI: A84041FDFE24D4F9

The gateway has been sold, but the new owner cannot register it because it is still associated with my TTN account.

Unfortunately, I cannot access my account anymore. Every login attempt ends with the following error:

error:pkg/web/oauthclient:no_state_param

(no state parameter present in request)

Correlation ID:
61442088da6d47ef8cd406d7ce1a509c

The problem occurs on multiple devices and networks (Windows, smartphone, mobile network), so it does not appear to be a browser issue.

Could you please either:

  • help restore access to my account, or

  • remove/release gateway lech01 (EUI A84041FDFE24D4F9) from my account so the new owner can register it?

Thank you.

TTN Core team rarely drive-by the TTN Forum, and TTN Forum Mods or Users do not have account access, so your best option for a response is try on the Things Slack using #support channel. (Or contact them directly for support but unlikely cost effective if you are no using account anymore or not active with TTN/TTI)
