Get a new key at ...' (401) / 'Access forbidden. Please check your browser-use cloud subscription status.' (403) / 'BROWSER_USE_API_KEY is require… ## Body Cause (Documented platform behavior): The cloud client maps HTTP 401 to an invalid-key CloudBrowserAuthError, 403 to a subscription-status error, and the @sandbox decorator requires BROWSER_USE_API_KEY before executing. Fix status: documented_behavior Limitations: - Source is the published browser-use 0.13.10 wheel from PyPI; behaviour may differ in other versions. - Not reproduced in this session. Other error fragments: - Access forbidden. Please check your browser-use cloud subscription status. - BROWSER_USE_API_KEY is required - Timeout while creating cloud browser. Please try again.
