@Tra ,

This is a problem with your version of Java, which is very old.

You must either upgrade Java to the Java 11 (or at least to the latest Java 😎 or install the JCE extension for your current JDK.

Please see details in here: https://community.cloudera.com/t5/Support-Questions/Nifi-starts-without-error-but-cannot-connect/m-p/338254/highlight/true#M232781

Cheers,
