Connection error in Mazda Update Toolbox
If the Mazda Update Toolbox shows a connection error when you open it, deleting a specific registration file from the SD card may resolve the issue.

What to do
- Close the Mazda Update Toolbox completely.
- Open the SD card in File Explorer on Windows or Finder on macOS.
- Open the following folder: /license/
- Delete only the following file: .reg
Important: Do not delete any other files from the SD card. - If you cannot see the .reg file, enable the option to show hidden files on your computer.
- Open the Toolbox again.
- Check whether the connection error still appears.
