Creating authorization failed

Trying to create a new user entry code via web.nuki.io, I get the message

Earlier, I’ve changed the name of smartlock.
In the web application I still see the old name.

Has the web app web.nuki.io lost its connection with the lock?

I urgently have to create several new codes via the web
Thanks for your help!

Sorry for the late reply. Do you see any error message on the detail view of the device?

In any case best contact our support via https://nuki.io/en/support-request/ or contact@nuki.io for direct help.

This forum is focused on developer related issues.

Or could you reproduce the same behaviour with the Web API (if yes with which error codes)?
