I do not see the other participants and I can not invite them

@Dele Olajide

Good Morning.
To begin I will put my network conditions:
Server

  • A virtual machine with 2Gb RAM VitualBox
  • Ubuntu Server 14.04
  • Openfire: 4.0.2
  • Ofmeet 0.3.20

PC Client

  • Chrome extension 50 with a camera with built-in microphone.
    When I access this address: https: // my-server: 7443 / ofmeet I get a web page that allegedly I put the name of the room and pressed “GO”.
    Instantly activates the camera and I see myself, but when I go to another PC with the same conditions for a customer and agree to the same address, ask me I login, it does but I can not see the other participants or members.
    And I do not know, I tried to Ofmeet 0.3.9, 0.3.17 and 0.3.19.

Greetings and please need your help.
Dionny
