Getting this exception during startup
ERROR [ACCEPT-/node1.example.com] 2020-09-04 07:48:43,605 MessagingService.java:1082 - SSL handshake error for inbound connection from 30a0f730[SSL_NULL_WITH_NULL_NULL: Socket[addr=/node1.example.com,port=45726,localport=7001]] javax.net.ssl.SSLHandshakeException: no cipher suites in common
Hi,
This error can be raised for multiple reasons (JVM, Keystore, configuration, certificates). Could you please provide more information about the environment you are using:
Also you can restart the application and enable the flag `-Djavax.net.debug=SSL,handshake,` for us to get more logs.
Thank you
To add to Cédric's response, we recommend that you use Oracle or OpenJDK 8 with at least update 161 since it includes the unlimited policy files required for use with the Java Cryptography Extension (JCE).
It is also important that you follow all the steps in the relevant procedures when configuring SSL for DSE. If you miss just one step or make one mistake, the whole setup will not work. This isn't an issue with DSE but is inherent in SSL and encryption frameworks.
If you still require assistance, please log a ticket with DataStax Support so one of our engineers can assist you directly. Cheers!
