Elementor – Writing permissions issues with the following directories/files Elementor uploads directory

Everytime i want to update an specific page on my wordpress site the page gets frozen and does not let me use the builder. On WordPress Dashboard I see this message: Writing permissions issues with the following directories/files Elementor uploads directory.

When i check the error logs i find the following:

`[error] 14605#14605: *52603 FastCGI sent in stderr: "PHP message: PHP Warning:
  file_put_contents(/var/www/corvettes2.performancecorvettes.com/public/wp-content/uploads/elementor/css/post-701.css): 
failed to open stream: 
Permission denied in /var/www/corvettes2.performancecorvettes.com/public/
wp-content/plugins/elementor/core/files/base.php` 

What i have tried so far:

1. I have make sure i have set the correct permissions on Folders and files (755 Folders & subfolders, 644 files)
2. I modify the max_input_vars to 1000 on the htaccess file
3. I have check the nginx conf file to make sure nothing is odd (still i don’t find anything wrong):
