Question:
FIWARE Wirecloud Mashup: NGSI Source + Public/Testing ContextBroker (Probable NGSI Proxy Issue)

Description:
I am trying to build a simple Wirecloud Application Mashup, with the "NGSI source" and "Map Viewer" components, like the one described here but using the testing service available at 130.206.80.40.
Since I am a newcomer to the FIWARE platform, I started by following these simple instructions and managed to successfully create a virtual (python) device, publish and read observations to/from it. Then, I played with the FIWARE Lab for a while and also managed to successfully use the "NGSI browser" and "Spy Wiring" widgets to read my device's data. Finally, when I tried to use the "NGSI source" operator to "automatise" the readings, nothing happened. Components configurations below:

NGSI Browser

NGSI server URL: http://130.206.80.40:1026/
Use the FIWARE credentials of the user: Yes
NGSI entity types: [LEFT_BLANK]
Id pattern: test123
Extra Attributes: temp

NGSI Source

NGSI server URL: http://130.206.80.40:1026/
NGSI proxy URL: https://ngsiproxy.lab.fiware.org (also tried other addresses, without success)
Use the FIWARE credentials of the user: Yes
Use the FIWARE credentials of the workspace owner: No (also tried with "Yes")
NGSI entity types: [LEFT_BLANK]
Id pattern: test123
Monitored NGSI Attributes: temp

Please note that the "NGSI Source" operator worked perfectly with its default configuration.

Moreover I've also read on jira.fiware.org that the ContextBroker must support HTTPS; does that mean that the public testing server doesn't support it and that I can't use it for my final purpose? Or there is a way to use it without the NGSI proxy (another operator perhaps)?

Thank you.
