Scenario: If you access a url with a trailing slash it causes the port number of nginx to be appended to the URL and in most cases either breaks the page or causes a blank page.

To fix this you need to configure nginx to prevent adding the port number when a redirection is caused by a trailing slash.

Add the following in your nginx.conf at /etc/nginx/

Restart nginx and subsequently varnish.
