error 404 Not Found nginx wp-admin is showing an error

Question

The site is working. But wp-admin is showing an error. Error defined as error 404 Not Found. What could be the reason for this. If I open wp-admin from site hosting then that wp-admin is opening. But from here wp-admin is not working.

Site : https://modafinilminds.com/wp-admin

I try to check files and try to fixed this issue and update .htaccess page.

My .htaccess Page :

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^en/wp-login.php /wp-login.php [QSA,L]
RewriteRule ^de/wp-login.php /wp-login.php [QSA,L]
RewriteRule ^ja/wp-login.php /wp-login.php [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
# BEGIN LiteSpeed
# The directives (lines) between "BEGIN LiteSpeed" and "END LiteSpeed" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule Litespeed>
SetEnv noabort 1
</IfModule>
# END LiteSpeed
    

So can anyone tell me what could be the reason for this. And how to fix this. Thanks in advance.
