Decided to code the problem.

The code to solve this problem is quite simple. Add the following code after HttpOpenRequest to set the current Http connection options to cancel this check

DWORD dwFlags = 0;

DWORD dwError = 0;

DWORD dwBuffLen = sizeof(dwFlags);
InternetQueryOption(m_hRequest, INTERNET_OPTION_SECURITY_FLAGS,

(LPVOID)& dwFlags, & dwBuffLen);

dwFlags |= SECURITY_FLAG_IGNORE_REVOCATION;

InternetSetOption(m_hRequest, INTERNET_OPTION_SECURITY_FLAGS, (LPVOID)& dwFlags, sizeof(dwFlags)) ;
