ERROR: SSL handshake failed: DH lib (wodWebServer / wodWebServer.NET)

Hello,

I am having a problem with an SSL handshake. The error only happens when I try to goto the website thru a socks4 proxy. It connects to the proxy. Sends the first packet and recieves the Z responce. When it tries to send the first packet that it would normally do when just connecting to the server it will respond with 'SSL handshake failed: DHlib' Here is the code I am using. I am using vb6.

frmMain.wodSSL(Index).ProxyHostname = sHTTP(Index).sProxyHost
frmMain.wodSSL(Index).ProxyPort = sHTTP(Index).iProxyPort
frmMain.wodSSL(Index).ProxyType = ProxySocks4
frmMain.wodSSL(Index).ProxyAuthentication = AuthNone

frmMain.wodSSL(Index).Request.Headers.RemoveAll
frmMain.wodSSL(Index).Request.Headers.Add Host , sHTTP(Index).sHOST
frmMain.wodSSL(Index).HostName = sHTTP(Index).sHOST

frmMain.wodSSL(Index).Secure = ProtTLS1

frmMain.wodSSL(Index).AutoRedirect = False
frmMain.wodSSL(Index).HTTPversion = HTTP/1.1

frmMain.wodSSL(Index).Request.URI = sHTTP(Index).sURL '/get.php

If sHTTP(Index).sAccept > Then frmMain.wodSSL(Index).Request.Accept = sHTTP(Index).sAccept

If sHTTP(Index).sPOST > Then
frmMain.wodSSL(Index).Request.Headers.Add Content-Type , application/x-www-form-urlencoded
frmMain.wodSSL(Index).Request.Body = sHTTP(Index).sPOST
End If

frmMain.wodSSL(Index).Request.UserAgent = sHTTP(Index).sUserAgent
If sHTTP(Index).sReferer > Then frmMain.wodSSL(Index).Request.Referer = sHTTP(Index).sReferer
If sHTTP(Index).sCookie > Then frmMain.wodSSL(Index).Request.Headers.Add Cookie , sHTTP(Index).sCookie

frmMain.wodSSL(Index).Request.Headers.Add Connection , Close
frmMain.wodSSL(Index).KeepAlive = Never

If sHTTP(Index).sPOST > Then
frmMain.wodSSL(Index).Post

Else
frmMain.wodSSL(Index).Get

End If

frmMain.wodSSL(Index).ProxyHostname = 198.110.164.4
frmMain.wodSSL(Index).ProxyPort = 443
frmMain.wodSSL(Index).ProxyType = ProxySocks4
frmMain.wodSSL(Index).ProxyAuthentication = AuthNone

Should work for a socks4 proxy.

Hi Mark,

Are you sure you send us correct proxy server information?

Here is code I try:
[code]http1.Blocking = True
http1.ProxyHostname = 198.110.164.4
http1.ProxyPort = 443
http1.ProxyType = ProxySocks4
http1.ProxyAuthentication = AuthNone
http1.Connect[/code]

When I execute that code I receive this error:

Proxy server rejected supplied login credentials.

Can you please check this out and let us know how can we connect there?

Also maybe you can send us site you are connecting though proxy. So we can duplicate your problem on our side.

Let us know how it goes.

Here try this.

Private Sub Command1_Click()

http1.ProxyHostname = 198.110.164.4
http1.ProxyPort = 443
http1.ProxyType = ProxySocks4

http1.Request.Headers.RemoveAll
http1.Request.Headers.Add Host , www.paypal.com
http1.HostName = www.paypal.com

http1.Secure = ProtTLS1

http1.AutoRedirect = False
http1.HTTPversion = HTTP/1.1

http1.Request.URI = /

http1.Request.UserAgent = Mozilla/4.0 (compatible; MSIE 5.0; Windows XP) Opera 6.05 [en]

http1.Request.Headers.Add Connection , Close
http1.KeepAlive = Never

http1.Get

End Sub

Private Sub http1_Done(ByVal ErrorCode As Long, ByVal ErrorText As String)
On Error Resume Next

On Error Resume Next

If ErrorCode = 0 Then
Debug.Print done right

Else
Debug.Print ERROR: & ErrorText
Exit Sub
End If

Debug.Print http1.Response.Body

End Sub

Private Sub http1_StateChange(ByVal OldState As wodHttpDLXLibCtl.HttpStates)

Debug.Print State changed to & http1.StateString(http1.State) & (old state was & http1.StateString(OldState) & )

End Sub

Here is the packets that are sents and recieved before the error.

Hi Mark,

I believe I duplicated this behaviour. However, if I switch to Socks5 is works like a charm, so I'm not really sure if it's problem with the component, since Mozilla has problem of displaying the same page thru Socks4 (displays fine with Socks5).

I've sent this to our programmers to check what exactly happens. We will inform you as soon as we know more on this.

I believe this is now fixed, can you request update and try with latest version?

Kreso

It works now. Thanks.
