Create a symlink to the actual CSV file location

ln -s /tmp/edx-s3/grades /edx/var/edxapp/media

Update location blocks in the Nginx file of lms (/edx/app/nginx/sites-avaliable/lms)

• Locate the following block in the file

    location ~ ^/media/(?P<file>.*) {
        root /edx/var/edxapp/media;
        try_files /$file =404;
        expires 31536000s;
    }
  

• Replace it with this one

    location ~ ^/media/(?P<file>.*) {
        root /edx/var/edxapp/media;
        try_files /$file /grades/$file;
        expires 31536000s;
    }
    location ~ ^/grades/(?P<file>.*) {
        root /edx/var/edxapp/media/grades;
        try_files /$file =404;
        expires 31536000s;
    }
  

Restart Nginx service

sudo service nginx restart
