SSL Proxy WP 3.4.2 HTTPS 3.3.6 -> Admin Login Prolbems

Usually this kind of thing happens when the redirect_to parameter on the wp-login.php page is incorrect. Try logging into just wp-login.php with no redirect_to parameter on it. Then trying browsing to /wp-admin/ and then logging in. If that’s the issue, /wp-admin/ may not work, but wp-login.php directly will work every time. Try it and let me know.

Great using wp-login.php instead of wp-admin solved also my Login Problem. Thanks.
