I create a block storage in Digital Ocean and copy my API to this storage and then create a symbolic link in my /var/www/html which goes to /mnt/volume-nyc1-01/api_cms, but when I try to access an internal folder, such as api_cms/uploads from the browser, I get error 403 and in the apache logs the message "symbolic link not allowed or link target not accessible apache2".
How can I make sure I can access the folders and files stored in the API from the browser and consequently from the application that uses this API?
