Description DiverseCG 2014-05-04 13:17:43 UTC
Description of Problem:
System.Net.HttpWebRequest fails with System.Net.WebException: The operation has timed out; Uploads with or without expect-100-continue fail if they take longer than 30 second timeout, even though the actual upload completes even if it takes 5+ minutes, the error happens on connection close, but the file is uploaded in it's entirety without any problems (hashes check out).  This error does not happen on Windows.  The error is painfully present with Duplicati backup software.  Unsure if related only to PUT requests. I have tried this on both MacOS and on Linux.  (error reports https://groups.google.com/forum/#!topic/duplicati/6jw0GKs8Bl8 and https://groups.google.com/forum/#!topic/duplicati/Rm5IJymLI9o )

Steps to reproduce the problem:
1. Do a backup with Duplicati software to Google drive or to SFTP, set the --dblock-size to a high enough value to make upload take > 30 seconds

2. try same backup command on Windows and see no errors

Actual Results:
System.Net.WebException: The operation has timed out

Expected Results:
no errors

How often does this happen? 
every time
