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

Issue

• The server’s encryption stack (OpenSSL library) is using a key that is not considered secure by Firefox, so the browser decided to disallow the connection. Why user is requesting us to adjust the SSL options to stop using DH Cipher?
