It is necessary to immediately run the updater to apply fixes that have not been incorporated into the initial installation.

sudo hzcms update

The default SSL certificate is a self signed certificate (aka snakeoil) meant for evaluation purposes only. Some browers will not accept this certificate and will not allow access to the site without special configuration (https://support.mozilla.org/en-US/questions/1012036).  For a production hub you will need to obtain a valid SSL certificate. A certificate may contain two or three pieces: a public certificate, a private key, and sometimes an intermediate certificate. All files are expected to be in PEM format.

Once you obtain the certificate, copy the SSL certificate files to the httpd SSL configuration directories and restart httpd.

sudo cp [your certificate pem file] /etc/httpd/conf/ssl.crt/hubname-cert.pem
sudo cp [your certificate private key pem file] /etc/httpd/conf/ssl.key/hubname-privkey.pem
sudo cp [your certificate intermediate certificate chain pem file] /etc/httpd/conf/ssl.crt/hubname-chain.pem
sudo chown root:root /etc/httpd/conf/ssl.crt/hubname-cert.pem
sudo chown root:root /etc/httpd/conf/ssl.key/hubname-privkey.pem
sudo chown root:root /etc/httpd/conf/ssl.crt/hubname-chain.pem
sudo chmod 0640 /etc/httpd/conf/ssl.crt/hubname-cert.pem
sudo chmod 0640 /etc/httpd/conf/ssl.key/hubname-privkey.pem
sudo chmod 0640 /etc/httpd/conf/ssl.crt/hubname-chain.pem
sudo hzcms reconfigure hubname
sudo service httpd restart

If you are using the HTML5 VNC Proxy Server, you must update your certificate settings there as well.
