password change nginx

[sscs12345]

When User logs in:
fpm-access.log
28/Mar/2020:03:02:32 +0000 "GET /login.php" 200
When Admin logs in:
fpm-access.log
28/Mar/2020:03:03:15 +0000 "POST /login.php" 302
28/Mar/2020:03:03:15 +0000 "GET /userpanel.php" 302
28/Mar/2020:03:03:15 +0000 "GET /login.php" 200

There is no line in fpm-access.log after clicking change password in userpanel. It just redirects to login.php
Works for admin panel
