Hi, Java ships cipher suites. We have printed all available cipher suites in our environment.
Tomcat is not able to enable SSL with JRE 1.8.0_333. The error says that the client and the server couldn’t find a common cipher suite. 1. Which cipher suite to be updated in tomcat to enable SSL ? 2. Where do we need to update the cipher suite in tomcat ? server.xml ? Please advise me if there is any other way to fix the SSL issue. Thank you in advance.
