Not Able To Download File Content In Microsoft Office 365 Account

Question

Hi,

I am trying to use this method to access file data.
API: GET/ https://graph.microsoft.com/v1.0/me/drive/items/{item-id}/content

I am using above API to get the Download URL and Location of the File for Office 365 account. When I am using the Download URL directly in the browser then the file is being downloaded easily, but when I am trying it through the code then it is throwing an exception as follows

Message: The underlying connection was closed: An unexpected error occurred on a send.
Inner Exception: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

The code snippet of the code is as follows:
