Add Item by Identifier not working

Hello, the add item by identifier is not working for me suddenly. I keep getting the error message "Zotero could not find a record for the specified identifier. Please verify the identifier and try again."

I was using the feature fine until yesterday. Please let me know if there is any way to sort it. I tried using the DOIS I had used before, and it still does not work.
