Smart Things: invalid_request

Hi,

i’ve a problem to integrate SmartThings again into HA. If i try to add the integration, i’ll be forwarded to the Samsung SmartThings page - After I select the location for a property access and click on authorize, I am redirected to the account-link.nabucasa.com where the error

“Oops… an error occured
invalid_request”

appears.

The error is in the URL:
Unable+to+find+any+configurations+for+app:+XXXXXXXXX-XXXXXX-XXXXXX-XXXXXXXX

is readable.

HA: 2025.3.3 / OS: 15.0
