[HELP] stuck on web ui

this is my first installation of ems trial version installing ems on vps 2 core 4 gb, running on centos 6.3, apache 2.2.5, php 5.6.0RC2 and got a few problems when access web ui with this message

Could not connect to 127.0.0.1!
Either EMS is stopped or the firewall settings (and/or SeLinux) of the target machine does not permit connection to port 7777.
Kindly consult the user manual

selinux status is disabled, firewall setting is accept input and output for tcp and upd on port 7777 when edit config.lua in cli aceptor session, protocol inbpundHttpJsonCli to port 1890, then service evostreamms restart and opening browser still got error message about port 7777 🙄 please help
