.htaccess on subdomain

hi hi have a site in subdomain :

https://subdomain.domain.eu
All file in public folder are insert into public_html
All other folder are inserted in a folder named codeigniter on same level of public_html.
fc path is set correctly : require FCPATH . '/../codeigniter/app/Config/Paths.php';
The site load correctly until login and redirect on index correctly but when i try to access

https://subdomain.domain.eu/controller/method
It redirect to https://subdomain.domain.eu/index.php always

this is my htaccess:

Code:

# Disable directory browsing
Options -Indexes

# ----------------------------------------------------------------------
# Rewrite engine
# ----------------------------------------------------------------------

# Turning on the rewrite engine is necessary for the following rules and features.
# FollowSymLinks must be enabled for this to work.
<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine On

# If you installed CodeIgniter in a subfolder, you will need to
# change the following line to match the subfolder you need.
# http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritebase
# RewriteBase /

# Redirect Trailing Slashes...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Rewrite "www.example.com -> example.com"
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]

# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to the front controller, index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([\s\S]*)$ index.php?/$1 [L,NC,QSA]

# Ensure Authorization header is passed along
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
ErrorDocument 404 index.php
</IfModule>

# Disable server signature start
ServerSignature Off
# Disable server signature end

in codeigniter folder i put another .htaccess:

Code:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteRule ^(.*)$ public_html/$1 [L]
</IfModule>

How can i solve ?
