I mean WINHTTP_OPTION_SECURE_PROTOCOLS. I wrote a test for this case and it fails on Windows with ERROR_WINHTTP_INCORRECT_HANDLE_TYPE. That means Wine behaves correctly here and the problem must be somewhere else.
Interesting.
I'll try to launch Skyrim SE in pure Windows and to test the same functionality if it is really broken.
