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

See this link, it worked for me: How to do HTTPS with TcpClient just like HttpWebRequest does?

Dim trust_all_certificates As New CertificateOverride
ServicePointManager.ServerCertificateValidationCallback = AddressOf trust_all_certificates.RemoteCertificateValidationCallback
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3

Public Class CertificateOverride

    Public Function RemoteCertificateValidationCallback(ByVal sender As Object, ByVal certificate As X509Certificate, ByVal chain As X509Chain, ByVal sslPolicyErrors As SslPolicyErrors) As Boolean

        'CertEXPIRED = 2148204801
        'CertVALIDITYPERIODNESTING = 2148204802
        'CertPATHLENCONST = 2148204804
        'CertROLE = 2148204803
        'CertCRITICAL = 2148204805
        'CertPURPOSE = 2148204806
        'CertISSUERCHAINING = 2148204807
        'CertMALFORMED = 2148204808
        'CertUNTRUSTEDROOT = 2148204809
        'CertCHAINING = 2148204810
        'CertREVOKED = 2148204812
        'CertUNTRUSTEDTESTROOT = 2148204813
        'CertREVOCATION_FAILURE = 2148204814
        'CertCN_NO_MATCH = 2148204815
        'CertWRONG_USAGE = 2148204816
        'CertUNTRUSTEDCA = 2148204818

        Return True

    End Function

End Class

P.S.

I inserted this line of code before just to be sure that the certificate from the server side is accepted: ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3
