Secure Connection Failed

Here is a link to my facebook page https://www.facebook.com/CoastalEnterprisesCompany
And the tab in question is the “Request a free sample” tab

I have been using this plugin for some time now and it has been working great. But recently I noticed when you click on the tab created I get the following message:

Secure Connection Failed
An error occurred during a connection to http://www.precisionboard.com.

SSL received a record that exceeded the maximum permissible length.

(Error code: ssl_error_rx_record_too_long)
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. Alternatively, use the command found in the help menu to report this broken site.

Why is this?
