Description of issue

Hi there, I am cannot run brew upgrade --cask synology-drive nor brew install --cask synology-drive (after uninstalling cask) due to:

Error: SHA256 mismatch
Expected: b6a1db799...
  Actual: 412481f324b...
    File:...
To retry an incomplete download, remove the file above.

I have tried force, update, update-reset and doctor to no avail.

When I tried to brew bump --open-pr --cask synology-drive, Terminal returns:

Error: Cask 'synology-drive' is unavailable: No Cask with this name exists.

Command that failed

brew install --cask synology-drive

Output of command with --verbose --debug
