Question:
cygnus instance not reached from orion context broker

Description:
I have installed cygnus 0.8.2 on fiware image CentOS-7-x64, I subscribed to orion context broker using:

(curl 193.48.247.246:1026/v1/subscribeContext s -S --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Fiware-Service: egmmqtt' --header 'Fiware-ServicePath: /egmmqttpath' -d @ | python -mjson.tool) <<EOF
{
"entities": [

"attributes": [
"switch2A"
],
"reference": "http://193.48.247.223:5050/notify",
"duration": "P1M",
"notifyConditions": [

],
"throttling": "PT1S"
}
EOF

No notification has reached cygnus and I got this error on orionContextBroker logs:

time=2015-10-06T17:43:37.898CEST | lvl=WARNING | trans=1443447780-161-00000000423 | function=sendHttpSocket | comp=Orion | msg=clientSocketHttp.cpp[358]: Notification failure for 193.48.247.223:5050 (curl_easy_perform failed: Couldn't connect to server)

I dont know why the cygnus instance is not reached under the associated public IP adress. In fact I can't ping cygnus machine instance from Orion instance. Any ideas of what I have missed? thanks!
