Ds-kv8213 After flashing the firmware, you cannot log in with an IP address

Hello, please help. Unable to connect to IP address after flashing firmware. It says HTTP error 404. So I can’t flash the correct Firmware. Please, can the error be fixed somehow, or can I just throw the device away? Thank you very much for your support. I uploaded firmware V2.2.5.6build 220607 there
