Hi, All!

Recently, during development of an application, I've started facing troublesome issue: calls to WinHTTP subsystem (specifically, WinHttpReadData/WinHttpQueryDataAvailable APIs) present me with 12004 ERROR_WINHTTP_INTERNAL_ERROR outcome. Doesn't happen always, problem is intermittent. Since this is a very generic error code, I'm out of options for debugging it. I'm wondering, whether there are logging options (Event viewer maybe) that could help in finding the cause? If so, how to turn it on, etc?

Best regards

    Hello @Ivanov,

    You can Collect WinHTTP traces using netsh.exe.

    There is also Capturing WinHTTP Logs document in WSDAPI Diagnostic Procedures.
