Resolved. If this can be useful to people who begin to test Zorro together with MT4 / MT5, copy the Zorro folder on the VPS installed on the c: .. it does not work, unlike what is written on the site, and there are errors. Tested with Amazon and other vendors. The simplest way, even if you have to wait 20 to 30 minutes, is to copy the Zorro setup file and install it inside the VPS.
The problem was solved several hours ago and it was not possible to write earlier because this site has problems with smartphone login. I hope the problems end here ... but I'm not a programmer
