After an update with Firefox, when I try to access a website that I had previous access, i get this error message:

Failed Secure Connection

An error has occurred during a united-login.ual.com connection. SSL received an ephemeral Diffie-Hellman key in the low setting message link "Server Key Exchange". (Error code: ssl_error_weak_server_ephemeral_dh_key)

    The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
    Please contact the web site owners to inform them of this problem.


I need access to this website and instructions on how to allow connection to this site.

hi vanessar, this means that the webserver you're trying to reach is vulnerable to the recently published logjam attack and therefore firefox won't connect: http://arstechnica.com/security/2015/05/https-crippling-attack-threatens-tens-of-thousands-of-web-and-mail-servers/

please report that to webmaster of the site in question to fix that issue...
