Create cluster with elasticsearch6.1.2

 I took a full day to create cluster with elasticsearch6.1.2 for testing. After I complete config and start every node.  I found some error messages in log file of every node , the error message is

"exception caught on transport layer [org.elasticsearch.transport.netty4.netty tcp channel@19d87229], closing connection invalid string; unexpected character: 253 hex: fd"

Can any people help me?   


very hard to tell what is going on. can you provide stacktraces or so?

Thank you, I had resolved this problem.
