Seeking Ubuntu Tomcat8 SSL Guide/Tutorial

Help
3

Thanks for the link.

I did following through the guide I’m getting the error:
“This site can’t be reached
ERR_TIMED_OUT”
I did change the Connector Port to 8443 from 443 as it was shown in the guide. Anyway, I have also tried port 443 and that didn’t work either.

I have checked my firewall settings and it allows both 8443 and 443.

Note that my Self-Signed certificate works on port 8443, so firewall isn’t the issue. But when I change the server.xml to point to the Let’s Encrypt certificate using the config example given here, I’m getting the ERR_TIMED_OUT error.

This is my server.xml looks like:

<?xml version='1.0' encoding='utf-8'?>
<!--

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->

  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

  </GlobalNamingResources>

                         certificateChainFile="/etc/letsencrypt/live/I-Placed-My-Domain-Here/chain.pem"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>
<Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>
    </Engine>
  </Service>
</Server>

Please note that I know my Let’s Encrypt Certificate works and the path is correct because on Apache2 I get valid certificate when I point the browser to https://MyDomain.com

Thanks in advance for any suggestion.
