This message indicates that the website is trying to set up a secure connection, but it is actually insecure because the SSL/TLS uses a Diffie-Hellman group size smaller than 1024-bit
Solution
As the SSL/TLS of that browser "Internet Explorer version 7 and Firefox version 3.6" uses a Diffie-Hellman group size smaller than 1024-bit so we need to change the current browser or update it
For Internet Explorer version 7 upgrade it to version 9
For Firefox version 3.6 upgrade it to version 4.7
Also this case may happen with other many different browser and at this case you need to update the browser to the latest one adn try again, or change it to one of the mentioned above
