Homebridge not showing up in Home app

I have homebridge running on a Raspberry Pi 2

I have the HTTP plugin installed and an accessories configured. Based on the above output it looks good

config.json

$ cat ~/.homebridge/config.json

      } 
    ]

}

Webserver is running:

$ curl http://localhost/device/projector/status
0

Firewall is completely open:

$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination 

I have delete the ~/.homebridge/persist directory and restarted homebridge

When I go to the Home app on my iPhone and click Add Accessory nothing shows up.

I don’t know what I am missing?

I found that if I changed the username and restarted home bridge it showed right up.
