Can't run project on server after migrating to VS2017

I have a ASP.NET Core project running on the .NET Framework 4.6.1 and after migrating to VS2017 it wont work on the server anymore.

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

Module  IIS Web Core
Notification    Unknown
Handler Not yet determined
Error Code  0x80070005
Config Error    Cannot read configuration file due to insufficient permissions
Config File \\?\C:\Users\*\Desktop\publish\web.config

What am I missing here?
