How to solve Error creating subscription in the context broker server: Connection Error? - fiware

Question

I'm trying to retrieve data from Orion context broker in Wirecloud via NGSI Source Operator. I run Orion broker in a VM-Centos.
The NGSI server URL is "http://192.168.2.129:1026".
The NGSI proxy URL is "https://ngsiproxy.lab.fiware.org".
The error "Error creating subscription in the context broker server: Connection Error' . What should i do?
Providing that when i write the IP in the browser, that's the result:
{
"orionError" :
{
"code" : "400",
"reasonPhrase" : "Bad Request",
"details" : "service not found"
}
}
The url is in the VM of the CB With the IP and port of the CB VM https://postimg.org/image/qgi5rlm1z/
The Error: "Error creating subscription in the context broker server: Connection Error” appears in the wiring on the wirecloud
The overall idea is that I have created entities successfully, I can register, update, sub and query But I need to see these results on the wirecloud..so I need to retrieve the data from the VM to the wirecloud to be visible on the NSGI browser Widget.
When I make the NSGI proxy setting to : https://ngsiproxy.lab.fiware.org → "Error creating subscription in the context broker server: Connection Error” https://s31.postimg.org/q50pe9d5n/image.png
When I change it to : https://mashup.lab.fiware.org:8443 → This appears https://s31.postimg.org/4ilox86vf/image.png

Answer 1

if you just type in the browser
http://192.168.2.129:1026 you will get the error you describe as no Orion service is invoked.
If you want to create a subscription you would need to do it directly to the Broker without passing through the NGSI Proxy. So you would need to
POST http://192.168.2.129:1026/v2/subscriptions using a payload similar to the one described at

I Hope this helps
