+### Using TLS communication

+In case the Netdata web server has been [configured to use TLS](../web/server/#enabling-tls-support),
+you must also encrypt the communication between Nginx and Netdata.

+To enable encryption, first [enable SSL on nginx](http://nginx.org/en/docs/http/configuring_https_servers.html) and then put the following in the location section of the Nginx configuration:

+proxy_set_header X-Forwarded-Proto https;
