hi, MBP 2017 stuck, cant reinstall macOS high Sierra

Hi, I cant reinstall MacOS high Sierra. I’ve done clean installation and using internet recovery. I’m getting this error message every single time “an error occurred while preparing the installation. try running this application again”. I’ve done the famous solution of setting the Date & Time on the Mac to be determined automatically with the terminal but with no success. What else can I do ? Please give me some help guys, I have som important work to do 😟
