Failed to open Session Handle (Windows 7 / Server 2008) #33
Description
Multiple Channels fail to create a session on Windows 7 / Server 2008. This appears to be an error in WinHTTP.
Tracing this through the Visual Studios debugger, I found that the exception was being thrown on the HTTPClient constructor.
An exception is thrown that gets caught here:
I also tried the Dropbox channel and received the error in the same part of the Dropbox channel.
My debugger doesn't enter the constructor when a breakpoint is set on it (for some reason I am not sure of), so I cannot quite tell what is wrong. But running net helpmsg 87 to get the error type, I can see that the exception is due to an invalid parameter. Googling "Failed to open Session", I find a couple references to the WinHTTP API.
