“413 Request Entity Too Large” in Nginx with “client_max_body_size” set

Modify NGINX Configuration File

sudo nano /etc/nginx/nginx.conf

Search for this variable: client_max_body_size. If you find it, just increase its size to 100M, for example. If it doesn’t exist, then you can add it inside and at the end of http

client_max_body_size 100M;

Test your nginx config changes.

sudo service nginx configtest

Restart nginx to apply the changes.

sudo service nginx restart

Modify PHP.ini File for Upload Limits

It’s not needed on all configurations, but you may also have to modify the PHP upload settings as well to ensure that nothing is going out of limit by php configurations.

If you are using PHP5-FPM use following command,

sudo nano /etc/php5/fpm/php.ini

If you are using PHP7.0-FPM use following command,

sudo nano /etc/php/7.0/fpm/php.ini

Now find following directives one by one

upload_max_filesize
post_max_size

and increase its limit to 100M, by default they are 8M and 2M.

upload_max_filesize = 100M
post_max_size = 100M

Finally save it and restart PHP.

PHP5-FPM users use this,

sudo service php5-fpm restart

PHP7.0-FPM users use this,

sudo service php7.0-fpm restart

It will work fine !!!
