Secure connection failed - assistance please

New server install - Sles 11 sp 3 OES 11 sp 2 on Dell Poweredge 2950
Original install included Firefox and I installed Dell's Open Manage Server Administrator.
Everything worked fine until an update (I believe Firefox was updated, but not sure because the version numbers look the same as my other servers)
Now when I try to open the Dell Open manage program, which is needed to configure my MD 3000 raid storage array I get the following error

Secure Connection Failed

An error occurred during a connection to localhost:1311.
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 contact the website owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.

Dell's site tells me to go into the Open Manage Administrator program and change the security settings, but I can't open the OMA to make that change.
Other searching tells me to disable weak ciphers in my "server.xml" file, but a search of the system shows 9 files named server.xml
so not only do I not know which file to change, I'm not really sure what change needs to be made. I'm still way too "novice" in my linux comfort level

Any assistance short of wiping the server - reinstalling - and making sure that firefox doesn't get updated would be appreciated, otherwise I guess I know how I'm going to spend my weekend.

Thanks
Dennis

You can go into firefox about:config and temporary change the settings so that you can access OMA: https://support.mozilla.org/en-US/questions/1065417
