When starting up Jira, an error is displayed blocking the startup. The error says server.xml has an issue with special characters then directs the admin to go https://confluence.atlassian.com/jirakb/changing-server-xml-to-handle-requests-with-special-characters-958453799.html.
Server setup:
Self-signed certificate for https
Https Port 8443
Here is the server.xml file that worked for me. I inserted at all Connector lines: relaxedPathChars="[]|" relaxedQueryChars="[]|{}^\`"<>"<?xml version="1.0" encoding="UTF-8"?><!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.
