You need to reset the permissions on /var/www/html back to 0755:

sudo chmod 755 /var/www/html

Explanation: the execute bit in file permissions (x) determines whether the contents of the directory can be enumerated. Turning this bit off (0644) will prevent the web server from being able to see what is in the directory.

The 2 commands ABOVE the one you quoted in the questions messed your system up.

These 2 fix permissions for directories and files:

sudo find /var/www/html -type d -exec chmod 755 {} \;
sudo find /var/www/html -type f -exec chmod 644 {} \;

---

Your

sudo chmod 644 /var/www/html

removed execute permissions for your directories.
