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

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.

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

kind regards,
