Possible reasons and solutions

i) SELinux settings enforcing a file serve

$ /etc/selinux/config

Change SELINUX = disabled within the file and check if this is the cause for the error

ii) Application directory under restricted user permission folder path

For example, configuring the django project inside /root folder and trying to serve those files via apache server (apache user).

Try changing the folder to a path that you think is good for allowing public access such /var/www or /opt/sites .

iii) File permission

Changing the read, write permission for the necessary files and folders

$ chmod -R 751 /home/mysite
