Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The examiner requires a substitute specimen because your specimen displays '.COM' while your drawing does not, and has also issued a duplicate registration refusal. This is a serious issue that requires attention.
