Health check at f5 load balancer is failing after upgrade to 7.13 from 7.6.2

BrahmaReddy Seelam - Consultant

We have upgraded JIRADC from7.6.2 to 7.13 .

• Initially we faced this issues ("2018-12-26 10:55:53,359 localhost-startStop-1 ERROR [c.a.jira.health.HealthChecks] Tomcat is misconfigured
  2018-12-26 10:55:53,359 localhost-startStop-1 ERROR [c.a.jira.health.HealthChecks] The server.xml file is missing parameters needed by Jira to handle requests that contain special characters.")   . fixed using the atlasian fix  FIX-server.xml-to-handle special-characrters.  After that individual nodes and individual fallback urls are working fine on port no.8080 and 8443.
• But the problem is F5 load balancer which was  working fine with 7.6.2 version is not resolving the health check with port 8443 , though 8080 health check is fine at F5 LB with version 7.13 .
• Health checks for individual nodes https://nl001572.tst.kohls.com:8443/  ,  https://nl001572.tst.kohls.com:8443/status are giving the output  {"state":"RUNNING"} . But at F5 only for port 8080 health check is resolving , for 8443 it is not resolving . 
• server.xml connector block is below.
