When upgrading from Jira Software from 8.15 to anything greater than 8.15, I can no longer access the web interface. We use https and I've
1. manually added the custom modifications to server.xml, web.xml, and verified jira-application.properties, and setenv.sh files.
2. used the config.sh to modify the web settings
3. check the service jira status and system is "online"
No matter what I cannot access the web interface. I've looked through the catalina.out logs but nothing is jumping out and screaming "FAILED"
The SSL cert is valid. I've ran through every help page I could find that is relevant to my issue. Any help would be greatly appreciated.
