Extra information: If I open IIS and got to SAP_Cache_Server -> Cache, select basic settings and then click on Test settings, I get the following authorization warning message
"The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again."
The feature permissions are Read, Script, Execute.
