HP Recommended
Product: Envy 7640
Operating System: macOS 10.15 Catalina
Apple has stated that macOS 11.6 fixes the error "Failed to open a connection to the device (-21345)" in the article 'You do not have permission to open the application' when using a scanner on Mac

 

using the latest MacOS 10.15.4, over a wifi network, the error occurs using scan link in printer control and HP Easy Scan and Image Capture. Printing works but can not connect to the scanner.
