I have seen a couple people had this problem, but a solution did not come to me.
I installed confluence on an aws instance ( ubuntu 16.04 ) and as far as i read the logs, i do not see an error.
i followed the instructions on https://confluence.atlassian.com/doc/installing-confluence-on-linux-from-archive-file-255362363.html
When i start the process i geht following lines in Terminal:
To run Confluence in the foreground, start the server with start-confluence.sh -fg
executing as current user
If you encounter issues starting up Confluence, please see the Installation guide at http://confluence.atlassian.com/display/DOC/Confluence+Installation+Guide
Server startup logs are located in /var/www/html/confluence/logs/catalina.out
