Can't get merge to run on AWS EC2 Ubuntu 14.04

After I tried to install 5.8.6 merge,

I have mainly followed the steps at https://confluence.atlassian.com/display/DOC/Installing+Confluence+on+Linux+from+Archive+File#InstallingConfluenceonLinuxfromArchiveFile-2.InstallJava and https://confluence.atlassian.com/ display / DOC / Start + Confluence + Automatically + on + Linux

I used confluence

as user and ran . confluence-start.sh

inside/usr/local/confluence/current/bin/

Almost immediately I get the following message and my user account is disconnected from confluence

and back toubuntu

confluence@ip-xxx.xxx.xxx.xxx:/usr/local/confluence/current/bin$ . start-confluence.sh

To run Confluence in the foreground, start the server with start-confluence.sh -fg
executing as current user

Then I tried ip address: 8090. I get nothing.

Please advise.

UPDATE
