After the 10.1 upgrade, we set up EM and WebView jetty servers for SSL using a company's custom certificate as done in previous CA APM version. But the authentication fails and EM log shows an exception error, "SSLHandshakeException: no cipher suites in common."
During an upgrade the lower version of .xml files are retained. Therefore, customized settings are not carried forward.
This is due to a known Defect 375441/375443 as documented in the 10.1 release notes:
Now after the upgrade, webview-jetty-config.xml and em-jetty-config.xml files have protocols and certAlias properties. After upgrade, locate webview-jetty-config.xml and em-jetty-config.xml in the backup folder. Copy the most recently customized values to config/webview-jetty-config.xml and config/em-jetty-config.xml respectively.
