SSL Configuration

Reality Hub, by default, uses HTTP port 80 to serve its front-end to browser. To encrypt the network traffic between the Reality Hub Server and the browser, you need to configure the SSL (Secure Socket Layer) layer.

To configure SSL, you must obtain a valid certificate from an authorized provider. Please consult your network administrator to get help obtaining the certificate.

Configuration Steps

• Install Reality Hub Server and set its HTTP port to a different one than your clients will connect. The port that clients will use will be configured in the Nginx configuration.

• Make sure that Reality Hub Server is accessible from the same host that it is installed on.

• Install Nginx Server

• Configure Nginx as below

• Restart Nginx

For Reality Hub version 1.3.0 and older, please make sure that your Nginx installation supports nginx_http_sub_module.
