Hello

I am trying to add node in elasticsearch cluster, when I restart elasticsearch service on data node it give below error.  
"[2021-07-09T18:14:25,561][WARN][o.e.t.TcpTransport] [NODE2] exception caught on transport layer [Netty4TcpChannel{localAddress=/X.X.X.X:38574, remoteAddress=IT-NODE1/X.X.X.X:9300, profile=default}], closing connection  
io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad\_certificate"

I have added SSL certificates to java keystores and both master node and data node can be accessed over SSL.

Please help.
