Hello All,

I have been trying to setup Confluence for a client in AWS but I have ran into several issues with no solution. Below is the error

Felix,

  I believe that this is a permissions issue.  Check and make sure that the files in the confluence home directory are created by the owner of the directory.  If not change the owner.  Someone had a similar problem in this thread. https://community.atlassian.com/t5/Confluence-questions/Confluence-Server-install-in-Docker-falure/qaq-p/458625

If it is not a permissions issue then it could be JMX but I bet it is permissions.  https://confluence.atlassian.com/confkb/unable-to-start-confluence-due-to-jmx-182158269.html?_ga=2.219498393.1840931089.1528731559-890520517.1523892346
