Resolving ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY error in Chrome version 45

Resolving ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY error in Chrome version 45


You will receive the error when the server is trying to setup a secure connection but due to a disastrous mis-configuration, the connection wouldn’t be secure. As of Chrome version 45, this error message is triggered if the SSL/TLS handshake attempts to use a public key smaller than 1024 bits. 

Please edit the Server.xml file from the "<Installation directory>\ManageEngine\AD360\conf\"  and add the given chipers

Example : 

<Connector SSLEnabled="true" ciphers= " TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA " acceptCount="100" clientAuth="false" connectionTimeout="20000" debug="0" disableUploadTimeout="true" enableLookups="false" keystoreFile="./conf/selfsigned.pfx" keystorePass="adventnet" keystoreType="PKCS12" maxSpareThreads="75" maxThreads="150" minSpareThreads="25" name="SSL" port="8445" scheme="https" secure="true" sslProtocol="TLS"/>

Please follow the steps provided below to modify SSL Connector.

* Stop AD360 (Click Start --> All Programs --> AD360 --> Stop AD360).

* Take a backup of the existing "server.xml" file located in <installation directory>\conf folder (C:\ManageEngine\AD360\conf) 

*  Edit the "server.xml" file to modify the SSL Connector which would be at the bottom of the page.

* Start AD360 (Click on Start --> All Programs --> AD360 --> Start AD360).
