When i try to login to admin panel, there is no error, just redirection again to login page. I cleared my cookies, tried different browser and checked my cookie domain settings in db - they are set correctly. Redirection happens beside if i provide correct or incorrect login information.
Site was working on 2.3.6 - after upgrading to 2.4.3-p1 this issue occurs. This is happening on Windows with xampp - i have second machine with linux that is working perfectly fine after upgrade. Front is working fine on Windows.
