Hello,
I am trying to connect to a host using Chillkat Socket v9.4.1 (ActiveX Version)
We are using SSL certificates and loading them successfully, but when we action the Connect method, it completes successfully (Connect method returns 1), but the Socket is not connected I can see no Errors anywhere in the Logs, (LastMethodFailed = 0, ConnectFailReason=0)
We have confirmed That there is no firewall issues, between us (client) and the host we are attempting to connect to.
I have seen That the logs state that a "Secure Channel was Established" - which would suggest that it has connected, but I cannot see any other evidence of this.
Can anyone tell me what may cause this bvehaviour? Any help would be greatly appreciated. Example code and results to follow below.
Thank you Andrew.
Set cert = New ChilkatCert
plngSuccess = chlSocket.UnlockComponent("UnlockCode")
chlSocket.Close 10000 'max time allowed is 10 seconds (function uses microseconds)
'if we have reached this point then we have a clean socket control in a not connected state
pstrRemoteIPAddress = "12.24.56.78"
pstrRemotePort = "12345"
plngSSL = 1
plngSuccess = cert.LoadByCommonName("MyCertificateName")
chlSocket.SetSslClientCert cert
chlSocket.ClearSessionLog
chlSocket.SessionLogEncoding = "hex"
chlSocket.KeepSessionLog = 1
chlSocket.VerboseLogging = 1
chlSocket.DebugLogFilePath = "D:\temp\chillkat\error.log"
chlSocket.ssl = plngSSL
chlSocket.SslProtocol = "default" '- the socket will determine the protocol once connected to server
chlSocket.SocksVersion = 4 'SOCKS4
chlSocket.SocksHostname = "myProxy.com"
chlSocket.SocksPort = "1080"
st = GetTickCount()
plngSuccess = chlSocket.Connect(pstrRemoteIPAddress, pstrRemotePort, plngSSL, 20000)
Debug.Print "IsConnected [" & chlSocket.IsConnected & "]"
Debug.Print "Success [" & plngSuccess & "] in [" & GetTickCount - st & "] millisecs"
If chlSocket.LastMethodFailed = 1 Then
i = 1
pstrMessage = ""
If chlSocket.IsConnected = 1 Then
Debug.Print "Connected but with errors"
Else
Debug.Print "Failed to connect"
End If
Debug.Print chlSocket.LastErrorText
GoTo FinishedSendTCPIPData
ElseIf chlSocket.IsConnected = 0 Then
Debug.Print "Not Connected"
Debug.Print chlSocket.LastErrorText
Else
Debug.Print "Connected"
End If
chlSocket.Close (10000)
chlSocket.Dispose

Turned out to be invalid Certificate Authentication. Although, It would have been nice to have some evidence of this on the Socket!
