Proxy error with Visual Studio to salesforce Authorization Failed but I have set proxy but not connected. can you please help me 

The current status of the remote service (an archiving service), including available space on the remote service
DropZonePageController uploads a file to the remote Service.
You should check the size of the file the user wants to upload.
  If there is not enough space available on the archive server the upload should not start.
