Server has a weak, ephemeral Diffie-Hellman public key

I encounter an access problem on vSphere Data Protection via the web browsers(chrome and firefox). It shows the captioned error.  However, it can be connected using IE.  My vSphere Data Protection is 5.5 and 5.8.  Please help.

Take a look at this for an explanation of how to disable the check in firefox [Solved] Server has a weak ephemeral Diffie-Hellman public key | Chrome Firefox Opera | Let's Explai... .  For vRO you can tweak the web server so it does not generate the error http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=213161... not sure if there is a similar fix on the back end for what you are running into.  You probably don't want to leave Firefox disabling that check for long.

Thanks for your help. But it doesn't work.  I also tried to change ciphers as below at /usr/local/avamar-tomcat/conf/server.xml using vi editor.  It shows "This webpage is not available".

ciphers="TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA" />
