"Server has a weak ephemeral Diffie-Hellman public key" geting this error while accessing cq instance in chrome

[smacdonald2008]

Is this happening on Author or Publish or both. Is this a fresh instance of AEM, or did this start when you placed custom code on the server. What version of AEM are you using. 

[Jörg_Hoh]

How you access the AEM instance? Directly or via dispatcher or loadbalanacer?

kind regards,
Jörg

both author and publish version 5.5

accessing the cq instance by url.

Hi 

Please have a look at this Stackoverflow post :-

Chrome:

• open /Applications/Google\ Chrome.app --args --cipher-suite-blacklist=0x0088,0x0087,0x0039,0x0038,0x0044,0x0045,0x0066,0x0032,0x0033,0x0016,0x0013

Canary:

• open /Applications/Google\ Chrome\ Canary.app --args --cipher-suite-blacklist=0x0088,0x0087,0x0039,0x0038,0x0044,0x0045,0x0066,0x0032,0x0033,0x0016,0x0013

For Firefox

• Go to about:config
• Search for security.ssl3.dhe_rsa_aes_128_sha and security.ssl3.dhe_rsa_aes_256_sha
• Set them both to false.

I hope this workaround would help you.

Thanks and Regards
