Question:
Error subscription in cygnus

Description:
I am having problems when creating a subscription in cygnus.
I really think the error is from the contextBroker since it appears in the log - this is the information that it shows:

Time = 2017-08-07T10: 48: 09.360Z | Lvl = WARN | Corr = N / A | Trans = 1502101560-775-00000000006 | From = pending | Srv = pending | Subsrv = pending | Comp = Orion | Op = AlarmManager.cpp [328]: notificationError | Msg = Raising alarm NotificationError http: // localhost: 5050 / notify: (
Easy_perform failed: Could not connect to server)

I have open ports.
My subscription status is failed.

How can I solve that?

EDIT

The creation is as follows:

{
"description": "A subscription to get info about Room1",
"subject": {
"entities": [

],
"condition":

},
"notification": {
"http":

,
"attrs": [
"temperature"
],
"attrsFormat": "legacy"
}
}

When I perform the subscription on fiwarelab in the orion machine already created if it works, but when I try on a machine centos 6 and performing the installation steps is when I get that error.

I have already solved the problem and it was setup.

The steps I followed with the following:

To install cygnus:

1st install java and maven as it puts on the web of fiware
2nd install with yum install cygnus
3º Install apache flume as it puts on the web of fiware
4th install mySQL
5th configure the agents

Everything works already.
