I'm using a VPN connection and since the latest Firefox update it is giving me an error when I try to connect:

Secure Connection Failed

An error occurred during a connection to *website* SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key) 

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.


Please provide a solution for this ASAP I need this for my work!

hi kaster14, if you receive that error code when accessing a site, 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...

Philipp,

Thanks for the info, that doesn't solve the problem though. I've managed to revert to the previous version of Firefox to solve the problem. I wish Firefox would give a warning instead outright blocking websites...
