HttpSendRequest fails with error code 12029 #15532

Hi there,
this is my first post here, so greetings to all.

Since a few days, out of the blue, I’m getting a HttpSendRequest error 12029 when installing a package. That’s from Windows 10 cmd.
The URL works in the browser though.

I did not change anything AFAIK. Might be there was a WIndows update meanwhile.

The text was updated successfully, but these errors were encountered:

Cause
This problem occurs because Windows is not configured to use TLS 1.2 or 1.3 protocol and the hosted site has disabled support for TLS 1.0 and 1.1 in their on-premises environment (TLS 1.0 and 1.1 are nearing end-of-life, not to mention a security risk and many hosting sites have started disabling/phasing it out).

Error «12029» is a WinHTTP error code that indicates that a socket connection failed because encrypted communication could not be established.

• Your browser (Chrome, Edge, FireFox, Brave, Opera, etc are independently TLS 1.2 and 1.3 enabled) works independently from Windows
• Windows and vcpkg uses the internal winhttp to download files.

I’m closing the issue. Obviously vcpkg is not involved. After downloading one or two files manually, package installation miraculously worked. I’m suspecting it’s the virus protection (Bitdefender). Not so much that it would block something (there would be an alert/report), I feel it’s more of a timing issue. Why that should lead to error 12029 I cannot conceive.

Error winhttp cannot connect 12029

This forum has migrated to Microsoft Q&A. Visit Microsoft Q&A to post new questions.

Question

I’m trying to use a service that requires a lot of requests, for which I’m using the WinHttp API.

The general pattern is:

1. Call WinHttpOpen

2. Call WinHttpConnect

5. Close request handle

6. Repeat steps 3, 4, and 5 lots of times for various requests

7. Close connect handle

8. Close session handle

Now the problem I’ve having is that in the loop for steps 3, 4, and 5, the call to WinHttpSendRequest will occassionally return false, with GetLastError returning 12029 (ERROR_WINHTTP_CANNOT_CONNECT). This always happens after a few minutes of it looping around sending requests, but seems random as to exactly when it occurs.

I have tried setting the timeout open on the connection, and tried adding code into the loop to say «every X requests, close the session/connection completely and re-open), but I still get this error after a few minutes.

Answers

I did some researches for this issue. Here is a summary.

1. Network issue. There is a misconfiguration at Network level. The Public IP was not responding to any traffic coming on 80/443.

2. You could use the Windows Firewall API to check if certain ports are open or if your program has access. You can also use the API to configure the firewall to allow your program access if necessary. Here are a few examples of using the interface:

Thanks for the tips, but looking at these, none of this explains the random nature of the problem. The requests will work — for a while — and then randomly fail.

I added a retry loop in at the request level, i.e. so that steps 3,4 and 5 will repeat the same request if WinHttpSendRequests returns error 12029 with a short pause before retrying. And only after 5 attempts will it give up. This seemed to make it last a bit longer, but eventually the same request failed 5 times in a row and my progam still fell over.

From MSDN document, the error code detects that the connection to the server failed.

I searched this topic, I am afraid that it is the root cause of this issue. The website you requested return a 301 Moved Permanently header, to get winhttp to honour that and redirect to the URL in the Location: header (the www.) you need to use WinHttpSetOption to set the appropriate WINHTTP_OPTION_REDIRECT_* option(s).

Thanks for trying, but this is very unlikely to be the solution as evidenced by the fact that, as already stated, the requests all go to the same host and only occasionally return the 12029 error. At which point repeating the «open request/send request/close request» with the exact same request will usually work (but sometimes requires more than 1 retry).

If the service was returning a 301 error, I would expect this to occur all the time (?)

Its always possible that this is an issue at the web service end of course — unfortunately I currently have only one environment to run on so James-Carter’s suggestions, while perfectly valid, are a bit difficult to try at the moment.

Error Messages (Winhttp.h)

The error values listed below are returned by GetLastError when one of the Microsoft Windows HTTP Services (WinHTTP) functions fails, and are also returned in the lower 16 bits of HRESULT error returns from the WinHttpRequest object.

Error values whose names begin with «ERROR_WINHTTP_» are specific to the WinHTTP functions. The WinHTTP functions also return Windows error messages where appropriate.

ERROR_WINHTTP_AUTO_PROXY_SERVICE_ERROR

Returned by WinHttpGetProxyForUrl when a proxy for the specified URL cannot be located.

ERROR_WINHTTP_AUTODETECTION_FAILED

Returned by WinHttpDetectAutoProxyConfigUrl if WinHTTP was unable to discover the URL of the Proxy Auto-Configuration (PAC) file.

ERROR_WINHTTP_BAD_AUTO_PROXY_SCRIPT

An error occurred executing the script code in the Proxy Auto-Configuration (PAC) file.

ERROR_WINHTTP_CANNOT_CALL_AFTER_OPEN

Returned by the HttpRequest object if a specified option cannot be requested after the Open method has been called.

ERROR_WINHTTP_CANNOT_CALL_AFTER_SEND

Returned by the HttpRequest object if a requested operation cannot be performed after calling the Send method.

ERROR_WINHTTP_CANNOT_CALL_BEFORE_OPEN

Returned by the HttpRequest object if a requested operation cannot be performed before calling the Open method.

ERROR_WINHTTP_CANNOT_CALL_BEFORE_SEND

Returned by the HttpRequest object if a requested operation cannot be performed before calling the Send method.

ERROR_WINHTTP_CANNOT_CONNECT

Returned if connection to the server failed.

ERROR_WINHTTP_CLIENT_AUTH_CERT_NEEDED

The server requires SSL client Authentication. The application retrieves the list of certificate issuers by calling WinHttpQueryOption with the WINHTTP_OPTION_CLIENT_CERT_ISSUER_LIST option. For more information, see the WINHTTP_OPTION_CLIENT_CERT_ISSUER_LIST option.

If the server requests the client certificate, but does not require it, the application can alternately call WinHttpSetOption with the WINHTTP_OPTION_CLIENT_CERT_CONTEXT option. In this case, the application specifies the WINHTTP_NO_CLIENT_CERT_CONTEXT macro in the lpBuffer parameter of WinHttpSetOption. For more information, see the WINHTTP_OPTION_CLIENT_CERT_CONTEXT option.

Windows Server 2003 with SP1 and Windows XP with SP2: This error is not supported.

ERROR_WINHTTP_CLIENT_CERT_NO_ACCESS_PRIVATE_KEY

The application does not have the required privileges to access the private key associated with the client certificate.

Windows Server 2003 with SP1 and Windows XP with SP2: This error is not supported.

ERROR_WINHTTP_CLIENT_CERT_NO_PRIVATE_KEY

The context for the SSL client certificate does not have a private key associated with it. The client certificate may have been imported to the computer without the private key.

Windows Server 2003 with SP1 and Windows XP with SP2: This error is not supported.

ERROR_WINHTTP_CHUNKED_ENCODING_HEADER_SIZE_OVERFLOW

Returned by WinHttpReceiveResponse when an overflow condition is encountered in the course of parsing chunked encoding.

ERROR_WINHTTP_CLIENT_AUTH_CERT_NEEDED

Returned by WinHttpReceiveResponse when the server requests client authentication.

Windows Server 2003 with SP1 and Windows XP with SP2: This error is not supported.

ERROR_WINHTTP_CONNECTION_ERROR

The connection with the server has been reset or terminated, or an incompatible SSL protocol was encountered. For example, WinHTTP version 5.1 does not support SSL2 unless the client specifically enables it.

ERROR_WINHTTP_HEADER_ALREADY_EXISTS

Obsolete; no longer used.

ERROR_WINHTTP_HEADER_COUNT_EXCEEDED

Returned by WinHttpReceiveResponse when a larger number of headers were present in a response than WinHTTP could receive.

ERROR_WINHTTP_HEADER_NOT_FOUND

The requested header cannot be located.

ERROR_WINHTTP_HEADER_SIZE_OVERFLOW

Returned by WinHttpReceiveResponse when the size of headers received exceeds the limit for the request handle.

ERROR_WINHTTP_INCORRECT_HANDLE_STATE

The requested operation cannot be carried out because the handle supplied is not in the correct state.

ERROR_WINHTTP_INCORRECT_HANDLE_TYPE

The type of handle supplied is incorrect for this operation.

ERROR_WINHTTP_INTERNAL_ERROR

An internal error has occurred.

ERROR_WINHTTP_INVALID_OPTION

ERROR_WINHTTP_INVALID_QUERY_REQUEST

Obsolete; no longer used.

ERROR_WINHTTP_INVALID_SERVER_RESPONSE

The server response cannot be parsed.

ERROR_WINHTTP_INVALID_URL

The URL is not valid.

ERROR_WINHTTP_LOGIN_FAILURE

The login attempt failed. When this error is encountered, the request handle should be closed with WinHttpCloseHandle. A new request handle must be created before retrying the function that originally produced this error.

ERROR_WINHTTP_NAME_NOT_RESOLVED

The server name cannot be resolved.

ERROR_WINHTTP_NOT_INITIALIZED

Obsolete; no longer used.

ERROR_WINHTTP_OPERATION_CANCELLED

The operation was canceled, usually because the handle on which the request was operating was closed before the operation completed.

ERROR_WINHTTP_OPTION_NOT_SETTABLE

The requested option cannot be set, only queried.

ERROR_WINHTTP_OUT_OF_HANDLES

Obsolete; no longer used.

ERROR_WINHTTP_REDIRECT_FAILED

The redirection failed because either the scheme changed or all attempts made to redirect failed (default is five attempts).

ERROR_WINHTTP_RESEND_REQUEST

The WinHTTP function failed. The desired function can be retried on the same request handle.

ERROR_WINHTTP_RESPONSE_DRAIN_OVERFLOW

Returned when an incoming response exceeds an internal WinHTTP size limit.

ERROR_WINHTTP_SCRIPT_EXECUTION_ERROR

An error was encountered while executing a script.

ERROR_WINHTTP_SECURE_CERT_CN_INVALID

Returned when a certificate CN name does not match the passed value (equivalent to a CERT_E_CN_NO_MATCH error).

ERROR_WINHTTP_SECURE_CHANNEL_ERROR

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).

ERROR_WINHTTP_SECURE_FAILURE

One or more errors were found in the Secure Sockets Layer (SSL) certificate sent by the server. To determine what type of error was encountered, check for a WINHTTP_CALLBACK_STATUS_SECURE_FAILURE notification in a status callback function. For more information, see WINHTTP_STATUS_CALLBACK.

ERROR_WINHTTP_SECURE_INVALID_CA

Indicates that a certificate chain was processed, but terminated in a root certificate that is not trusted by the trust provider (equivalent to CERT_E_UNTRUSTEDROOT).

ERROR_WINHTTP_SECURE_INVALID_CERT

Indicates that a certificate is invalid (equivalent to errors such as CERT_E_ROLE, CERT_E_PATHLENCONST, CERT_E_CRITICAL, CERT_E_PURPOSE, CERT_E_ISSUERCHAINING, CERT_E_MALFORMED and CERT_E_CHAINING).

ERROR_WINHTTP_SHUTDOWN

The WinHTTP function support is being shut down or unloaded.

ERROR_WINHTTP_TIMEOUT

The request has timed out.

This error can be returned as a result of TCP/IP time-out behavior, regardless of time-out values set in Windows HTTP Services.

ERROR_WINHTTP_UNABLE_TO_DOWNLOAD_SCRIPT

The PAC file cannot be downloaded. For example, the server referenced by the PAC URL may not have been reachable, or the server returned a 404 NOT FOUND response.

ERROR_WINHTTP_UNHANDLED_SCRIPT_TYPE

The script type is not supported.

ERROR_WINHTTP_UNRECOGNIZED_SCHEME

The URL specified a scheme other than «http:» or «https:».

 // Close any open handles.
 if( hRequest ) WinHttpCloseHandle( hRequest );

can someone give me an idea why this only works with microsoft.com? and how would i go about fixing it?
