Problem

If Jenkins is running behind nginx, you might encounter the error 'Nginx 413 Request Entity Too Large'.

Solution

To be able to install the Sealights plugin you need to update the nginx.conf or the specific website config under nginx/conf.d with the following line

client_max_body_size 3M;
CODE


Once configuration updated restart the nginx service by running the command below (works on most of the systems) *might require sudo privilege elevation:

sudo service nginx restart
			or 
sudo systemctl restart nginx
			or
sudo /etc/init.d/nginx restart
