Wowza Community

wowza not working

i rent 3 cloud servers and install wowza to all. But i can reach web interface only 1 server.

Other 2 can’t load web interface. What feature i missing? I check in my Linux with “top” command but i didn’t see wowza running in my system. I try stop and start them many time but can’t get it. How do i can config my server? and how to check?
