Hi @KoettingSimon as suggested I have got separate ssl certificates for node1 and node2 and I have configured node1 ssl certificate in node1 and likewise for node2.
However, I am receiving the below error now:
[server] failed to establish trust with server at []; certificate is not trusted in this ssl context ([xpack.security.transport.ssl])
