Winhttp.winhttprequest An Error Occurred In The Secure Channel Support
a community of 4.7 million programmers, just like you, helping each other. Join them; it only takes a minute: Sign up vb6 winhhtp: Error Occurred in the Secure Channel Support up vote 1 down vote https://support.microsoft.com/en-us/kb/181147 favorite I wrote a VB6 program which uses winhttp.dll to send and receive messages to/from a remote server. It has been working fine from various operating systems: Windows 2000, WinXP, Win7, Win8. Recently the server provider informed me that they will "phase out support of SHA-1 security certificates" and i need to "check that the thumbprint is aligned to SHA-2 new SSL cert.". What is happening now is that when my http://stackoverflow.com/questions/29688026/vb6-winhhtp-error-occurred-in-the-secure-channel-support program runs on WinXP,7,8 - it's still OK. But when running on Windows 2000, when I call the winhttp Send() method, I get an exception "Error Occurred in the Secure Channel Support". I am failey clueless on certificates etc and I don't really know what to do. My Vb6 code looks as follows: ' Connect to server Set m_ServerObj = New WinHttpRequest m_ServerObj.Open "GET", m_ServerURL_SC ' Send request to server m_ServerObj.Option(WinHttpRequestOption_SslErrorIgnoreFlags) = &H3300 'Unknown certification authority (CA) or untrusted root 0x0100 'Wrong usage 0x0200 'Invalid common name (CN) 0x1000 'Invalid date or certificate expired 0x2000 m_ServerObj.Send xml The error occurres when Send is called ssl vb6 winhttp share|improve this question asked Apr 17 '15 at 0:05 yaronkl 75210 Please let us know if you ever succeed in correcting the issue, or otherwise if you ever find what exactly was causing the error. Thanks! –johnwait Apr 17 '15 at 20:16 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted ERROR_WINHTTP_SECURE_CHANNEL_ERROR: This is a generic error thrown whenever Schannel.dll encounters a SSL version / feature / cipher / key-length / etc. it doesn't understand or support, or when the server (in the case of a client) will not negotiate for anything the c
RequestI have a classic ASP website running on a Windows Server 2012 box. One page makes a HTTP request to another application over https using code like this: Sub ShopXML4http(url,inStr, http://www.unknownerror.org/opensource/rxi/classic/q/stackoverflow/21354992/an-error-occurred-in-the-secure-channel-support-classic-asp-http-request outStr, method,xmlerror) Dim objhttp Set objhttp = Server.CreateObject ("MSXML2.ServerXMLHTTP.6.0") objHttp.open method, url, false If Method="POST" Then objHttp.Send instr Else objHttp.Send End if outstr=objHttp.responseText Set objhttp=nothing End Sub This code works http://www.tek-tips.com/viewthread.cfm?qid=1741135 fine almost all of the time (thousands of requests per day), but sporadically it will fail with a message like this: Number: -2147012739 Description: An error occurred in the secure an error channel support Source: msxml6.dll The application was recently moved from an old Windows 2003 Server to the 2012 Server, and this issue never seemed to be a problem on the old server. In addition, while this error is happening on the website, I could run the exact same code in a VBScript and it works fine. Resetting the application pool an error occurred seems to cause the site to be able to do the secure HTTP requests again (although it often fixes itself before I can get to the server).
iisasp-classicxmlhttprequestwindows-server-2012 3 Answer Stephen Quan Troubleshooting error codes: -2147012739 is a HRESULT. In hexadecimal that's 0x80072F7D. Look at the LOWORD: 0x2F7D. Convert that back to decimal: 12157. Lookup 12157 error codes. Find that it matches: ERROR_WINHTTP_SECURE_CHANNEL_ERROR A bit of Google-fu finds http://msdn.microsoft.com/en-us/library/windows/desktop/aa383770(v=vs.85).aspx which states: ERROR_WINHTTP_SECURE_CHANNEL_ERROR 12157 Indicates that an error occurred having to do with a secure channel (equivalent to error codes that begin with "SEC_E_" and "SEC_I_" listed in the "winerror.h" header file). However, you already discovered this as the message you got was "Description: An error occurred in the secure channel support". So this leads us right back where we started. The other observation I make is that your code is a non-asynchronous WinHTTP request (I know it has to be to function inside ASP), but, the concern is, due to the high frequency, your machine could be processing more than one WinHTTP request concurrently.

This data is details and GPS locations of a number of vehicles (Buses) I can read it with Firefox opening with Notepad and see it is binary with some printable text. If I open with Internet Transfer or Webbrowser I get a blank screen If I open with IExplorer (ver 6 in my XP machine) I get the "Cant open" notice. Is there a way to open it with Winsock and read to a stream in Vb6, erasing the stream as I read each vehicle? What port would I use? Do I have to send it some code once connected to start it downloading? This is the URL: https://gtfsrt.api.translink.com.au/feed This is the sender's description "The feed is an actual continuous stream which is in Protocol Buffer (Googles simplified XML platform) and has to be queried continuously" I would have no trouble decoding and handling the data in vb6 once I could receive it. I am not very familiar with HTML so any help would be appreciated. RE: Problem reading data from internet strongm (MIS) 25 Nov 14 04:57 Add a referencwe to the Microsoft WinHTT
