Hi all,

We update last night our Google Chrome Apps to last version (45.0.2454.85).
But since, we can't acces JSS anymore from Chrome.

Here is what the error message says : "Server has a weak ephemeral Diffie-Hellman public
ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY"

We already find how "fix" that message on Firefox, by changing those keys :
security.ssl3.dhe_rsa_aes_128_sha
security.ssl3.dhe_rsa_aes_256_sha

from true to false in user prefs.
We use a self signed certificate for the JSS.
But I can't find any information on how disable that on Chrome.

Does anyone could help ?

    I think we simply removed those from the tomcat config for each of our webapps. Is there a reason you can't do that?

    I followed the Cipher changes for 9.73 and everything works now.

    Got hit by this also with Chrome 45 this morning. Follow what @djwojo posted and you'll be fine. Make a backup just in case.

    We had the same issue happened. I freaked out and contacted support. Here is the solution. I tested it and it worked great for both newest versions of Chrome and FireFox.
