Configure JIRA DC on single node without SSL on application level + F5 load balancer with SSL cert

[Alexandra Mihaela Apostol]

Hello,

I am trying to configure JIRA JSM 10.3.12 DC on single node (on a server) to run without the SSL certificate installed on the application level. we want to have the F5 load balancer 

I'm just trying to avoid installing an SSL certificate directly on the Jira server that was installed in the http://jira-dev.com:8081 and I want through the F5 that the certificate is installed to be access through https://jira-dev.com 

The F5 load balancer is listening on port 443, and it shows the Availability: Offline (Enabled) The children pool member(s) are down.
 
What am I doing wrong?
In the server.xml file I have these connector ports:

<Connector port="8080" relaxedPathChars="[]|" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"
maxThreads="200"
minSpareThreads="25"
connectionTimeout="60000"
enableLookups="false"
maxHttpHeaderSize="8192"
protocol="org.apache.coyote.http11.Http11NioProtocol"
useBodyEncodingForURI="true"
redirectPort="8443"
acceptCount="100"
disableUploadTimeout="true"
scheme="https"
proxyName="jira-dev.com"
proxyPort="443"
secure="true"/>


<Connector port="8081" connectionTimeout="20000" maxThreads="200" minSpareThreads="10"
enableLookups="false" acceptCount="10" URIEncoding="UTF-8"
relaxedPathChars="[]|" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"/>

<Connector port="8009" relaxedPathChars="[]|" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;" maxThreads="200" redirectPort="8443" packetSize="32768" enableLookups="false" protocol="org.apache.coyote.ajp.AjpNioProtocol" URIEncoding="UTF-8" secretRequired="false"/>
<Engine name="Catalina" defaultHost="localhost">
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">


Also, on the Apache httpd server, I do not have a /etc/https/conf.d/ssl.conf file but I have only a /etc/https/conf/virtual_hosts.conf file.

The port 443 is open, but when I do a 
netstat -tulnp | grep 443 

nothing shows up...

How can I make this work?

Thank you in advance!

BR,
