WININET_E_LOGIN_FAILURE

WININET_E_LOGIN_FAILURE is a WinINet HRESULT. It means that the target server or proxy rejected the authentication request. The underlying cause can be invalid credentials, missing permissions, an unsupported authentication method, or a challenge that the application did not handle.

What to check

Capture the HTTP status and authentication challenge headers, such as WWW-Authenticate or Proxy-Authenticate.
Verify that the selected authentication scheme and credential source are supported by the target.
Check authorization and account-policy logs on the server or proxy when the supplied credentials are known to be valid.
