Hi ,

Tomcat instance failing after enabling SSL certificate .

However when I try the below approach in the server.xml comments, Tomcat does not
start:



[root@porsche conf]# cat server.xml
<Connector
protocol="org.apache.coyote.http11.Http11NioProtocol"
port="8443" maxThreads="200" compression="on"
scheme="https" secure="true" SSLEnabled="true"
keystoreFile="conf/keystore.jks" keystorePass="XziIPXoTSoF=OK0"
clientAuth="false" sslProtocol="TLS">
<UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
</Connector>
[root@porsche conf]#

[root@porsche conf]# ll keystore.jks
-rw-r-----. 1 root root 5470 Apr 5 16:23 keystore.jks
[root@porsche conf]# pwd
/opt/tomcat/conf
[root@porsche conf]#

after enabling server.xml modification fails to start
