Question:
Creating NGSI Source subscription in wirecloud mashup

Description:
I must admit I'm missing some points in creating an NGSI Source subscription for a wirecloud mashup. I tried the Wirecloud Basic History Info tutorial, tried my own deployed instance of Orion CB, tried creating subscription for both Manchester and Eindhoven cities' orion endpoint but nothing actually work: Here's the attempts I made for each case:

Wirecloud User Guide Basic Tutorial (History Info -settings created as described here):

NGSI server URL: http://orion.lab.fiware.org:1026/

NGSI proxy URL: https://ngsiproxy.lab.fiware.org

Use the FIWARE credentials of the user: Enabled

Use the FIWARE credentials of the workspace owner: Disabled

NGSI tenant/service: Emtpy

NGSI scope: /

NGSI entity types: Node, AMMS, Regulator

Id pattern: Empty

Monitored NGSI attributes: Latitud, Longitud, presence, batteryCharge, illuminance, ActivePower, ReactivePower, electricPotential, electricalCurrent

Unfortunately, after adding the NGSI Entity to PoI and creating settings as described in the Guide, PoI are not displayed on map as it is on the guide. Instead, I get the following error (NGSI Source operator logs):

Error creating subscription in the context broker server: Unexpected response from WireCloud's proxy

2. Own instance of Orion CB:
Added the following settings to the NGSI Source operator (NB: my orion instance is hosted by server ip 193.136.xx.xx):

NGSI server URL: http://193.136.xx.xx:1026/

NGSI proxy URL: https://ngsiproxy.lab.fiware.org

FIWARE-Service: environment

FIWARE-SERvicePath: /basic

NGSI Entity types: WeatherObserved

Monitored NGSI Attributes: location, temperature, relativeHumidity

I then get following error as well:

Error creating subscription in the context broker server: Connection Error

What exactly am i doing wrong here please?
