OAuth2 Credentials Always Use oauth.n8n.cloud Redirect Instead of My Workspace

I’m on n8n Cloud using a custom workspace domain:
https://cademanley.app.n8n.cloud

Whenever I create a new OAuth2 credential (including the built-in QuickBooks Online OAuth2), n8n auto-generates the redirect URI as:

https://oauth.n8n.cloud/oauth2/callback:

I’ve:

  • Deleted all previous credentials
  • Created new ones from within the workspace
  • Cleared cookies, tried Incognito
  • Verified my Intuit Developer app is correctly configured
  • Logged in through cademanley.app.n8n.cloud only

Still, the OAuth2 redirect remains incorrect. This is blocking me from authenticating with QuickBooks, which requires an exact redirect URI match.

Can someone from the team help patch my workspace so that credentials use the correct redirect?

Thanks so much!

Cade
