I have the same problem not working on 4.4, did you manage to solve this issue somehow?
Well, I just tried, and the login worked, but it redirected to a bad url, however the siteurl value did not get updated this time, so changing it back to the real value including http:// it fixed it for now.
Also I commented 2 lines on wp_login.php earlier:
//if ( $url != get_option( ‘siteurl’ ) )
//update_option( ‘siteurl’, $url );
I guess that also may have helped
Lets see if it works tomorrow, thanks!
