Failed to process request. 'ZipArchive::open(): Empty string as source'. The remote server returned an error: (500) ZipArchive::open(): Empty string as source.

I created issue #38, i managed to "partially" solve it (now if i enter wrong API key i'll get error), i added this line in nuget.conf:

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; under location = /index.php but now getting this, have no any PHP experience so no idea how to troubleshoot it.

 nuget push chocolatey.0.10.11.nupkg -s http://192.168.1.163 -apikey 12345 -verbosity detailed
