The operating system for ZED-Bull shows that it's loading, but there is something about the token machine request.
I recommend checking the documentation files provided by the developer of ZED-Bull on the official website. You will have all the necessary instructions to diagnose and fix any problems encountered while using the software. If you are an active customer you can also get in touch with them using the same website.
