how to change remote jira http to https

[Fayaz Abdul]

Hello

I am running jira on server, link is like: http://35.1**.2*.30:8080/ where am trying to access my jira with https.
I have followed many atlassian documents and created SSl certificate using letsencrypt and generated files in /etc/letsencrypt/live/jira.tafzs.com/
cert.pem

chain.pem

fullchain.pem

privkey.pem files in it.
And followed this link.

And added following lines:

<!--<Connector acceptCount="100" bindOnInit="false" connectionTimeout="20000" disableUploadTimeout="true" enableLookups="false" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" port="8080" protocol="HTTP/1.1" redirectPort="8443" relaxedPathChars="[]|" relaxedQueryChars="[]|{}^\`&quot;&lt;&gt;" useBodyEncodingForURI="true"/> -->

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
relaxedPathChars="[]|" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"
maxHttpHeaderSize="8192" SSLEnabled="true"
maxThreads="150" minSpareThreads="25"
enableLookups="false" disableUploadTimeout="true"
acceptCount="100" scheme="https" secure="true"
sslEnabledProtocols="TLSv1.2,TLSv1.3"
clientAuth="false" useBodyEncodingForURI="true"
keyAlias="jira" keystoreFile="/var/atlassian/application-data/jira/jira.jks" keystorePass="password" keystoreType="JKS"/>

Now my jira is not able to run.
please let me know why this happens and what needs to be done?

FYI:
keytool -list -alias jira -keystore /var/atlassian/application-data/jira/jira.jks
Enter keystore password:
jira, 25 Apr, 2019, trustedCertEntry,
Certificate fingerprint (SHA1): 62:41:C3:C1:FB:7A:*.*..*....:11:B0:81:1D:1F:41

Thanks

What are the symptoms of "not able to run"?  What does the log file say?
