Failure on HttpWebrequest with inner exception Authentication failed because the remote party has closed the transport stream

Question

Using C#, .Net 4.5, I\'m trying to send out a web request through HttpWebRequest on a remote server. Please see the code below. I tried most of the solutions suggested by s

Answer 1

I just want to share that this issue has already been resolved.

I just modified the part of the code where I set the security protocol before issuing the web request.

From:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

To:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;

As it turned out, vCenter 5.5 uses TLS as its SSL protocol in its configuration. I hope people may find this helpful when they encounter this same issue.
