SSL Handshake error while adding node to elasticsearch


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: 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.
