Not enough detail for a succinct answer.
To cut the problem in-half, try to browse http address of the backend server?
Another important consideration, Have you properly configured, /etc/varnish/user.vcl ?
Here is a Varnish tutorial… https://www.linode.com/docs/websites/varnish/getting-started-with-varnish-cache/
Finally, find the location of the Varnish log file to get more details.
