How can i resolve upload_max_filesize issue

Question

I have faced issue of upload_max_filesize , I have updated php.ini file on server with adding following.

memory_limit = 500M
post_max_size = 500M
file_uploads = On
max_execution_time = 600
max_input_time = 900
upload_max_filesize =500M

Also I have updated .htaccess file like..

<IfModule php7_module>
   php_flag display_errors 
   php_value post_max_size 500M
   php_value max_execution_time 330
   php_value max_input_time 260
   php_value max_input_vars 1000
   php_value memory_limit 500M
   php_value session.gc_maxlifetime 1440
   php_value session.save_path "/var/cpanel/php/sessions/ea-php70"
   php_value upload_max_filesize 500M
</IfModule>

But still i am getting same error The uploaded file exceeds the upload_max_filesize directive in php.ini , I just trying to upload 2MB video but getting same error.

Why does it i happen i don't know , I have also words with server support center and they told me that they have set 500MB max_upload_size.
