Got this error message when using mozilla firefox.
Secure Connection Failed
An error occurred during a connection to shop.hughesnet.com. PR_CONNECT_RESET_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
When Firefox connects to a secure website (the URL begins with "https://"), it must verify that the certificate presented by the website is valid and that the encryption is strong enough to adequately protect your privacy. If it is unable to verify this, Firefox stops connecting to the site and will show you an error page with the message, Warning: Potential Security Risk Ahead.
Nothing else for me to say.
That site is definitely missing its certificate.
