Description

When I click “Sign in” on the Owner Dashboard page of my published app, it redirects to a blank page instead of loading the dashboard. This happens every time, with no error message shown other than occasional 520 errors

I need to sign in to this dashboard to upload product photos for my LEGO rental catalog, so this is blocking me from completing my app before launch. This issue has also consumed a significant amount of my available credits during troubleshooting attempts.

  1. Open the Owner Dashboard URL above.
  2. The page shows “Owner access only” with a “Sign in” button.
  3. Click “Sign in.”
  4. Its a blank Screen
  5. Sometimes a 520 error appears briefly before or during this process.
  6. The dashboard never loads, regardless of how many times I retry, use a different browser, or use incognito mode.
