The requested URL was not found on this server.

Hi, friends i have one issue in accessing the apllication
on localhost works fine using Laragon, whereas in the server it displays error (The requested URL was not found on this server.) after the login submit button.
i have changed the config file to the default of CI but the issue is the same. also, the mos_rewrite is enabled in apache.
on .htaccess i have added the following settings
RewriteEngine On
RewriteCond $1 !^(index.php|resources|robots.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]

what could be the issue?
