Thanks Peter for the link and it worked like a charm. I am running the
tomcat version 9.0.56 on CentOS Linux release 7.9.2009 (Core). I have
enabled the TLSv1.3 protocol as per the below block but when I ran the scan
https://www.ssllabs.com/ssltest/analyze.html, It says *TLS 1.3 -> No* as
per the below scan results.
<Connector port="443" protocol="HTTP/1.1"
connectionTimeout="20000"
SSLEnabled="true" scheme="https"
ciphers="ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384"
keystoreFile="ssl/hsbcconsent.jks" keystorePass="tomcat" clientAuth="false"
disableSessionTickets="true" honorCipherOrder="true"
*SSLProtocol="TLSv1.2+TLSv1.3"*
redirectPort="8443" />

comment and guide me. Thanks in advance
