Chart preview don't function

[nevaring]

During new chart creation - preview windon show error
Request failed with status code 403
Only one working way to check - save chart and open to view in new tab.
Something wrong with VM settings, I guess. Maybe somebody can advise somithing to check?

With pie charts this trick working well, but with line chart even worse - When I tried to save chart - chart crreation window close and show error picrure with message "An error occurred"
