Question:
Fiware Orion subscription creation failed

Description:
Trying to create subscription on Fiware Orion to notify Cygnus instance. But no matter what i try or do i get failed as subscription status.

Main problem seem to be Cygnus URL i am using for notification, but cygnus i up and running without any issues and this problem still persist.

Fiware Orion version:

"orion" :

Fiware Cygnus version:

version 1.9.0_SNAPSHOT.887d615a9dfc2c09c99e511f8cefb148aa54809e

Fiware Orion error log:

time=Thursday 27 Sep 13:33:09 2018.712Z | lvl=WARN | corr=N/A |

NotificationError http://172.20.0.2:5050/notify: (curl_easy_perform

Subscription body:

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

],
"condition":

},
"notification": {
"http":

,
"attrs": [

]
},
"expires": "2040-01-01T14:00:00.00Z",
"throttling": 5
}

I found good amount of simmilar problems they all point out to url issues of Cygnus because it is run as docker container.
But u can see in logs and example that i use ip adders of containers(not localhost etc), and issue is constant.

What did i miss here since there is no much to do with subscription creation and it looks very simple but still all subscription are getting back with failed as status and issue i describe above.

Thanks.
