N8n connection err

Technical Q&A

Im trying to get API credentials with OAUTH2 in n8n

I tried it on my dev store and everything works just fine, but when I tried it on a real shop, I get this error:

[TFA] Unauthorized Access. This store requires two-factor authentication

I did everything the same..Both shops don’t have 2FA, also I tried with and without 2FA and the error stays the sameI even tried to add 2FA to n8n, but it didn’t helpThe app is 1-2026 version

Maybe its because of the enviroment differences? production vs dev?

Thanks

I created the app via dev dashboard, granted all scopes and distributed it via a link for one shop or multiple plus shops from the same organization.

I authenticate n8n via OAuth2:
