Question:
Can't show a PoI in the Wirecloud MapViewer widget

Description:
Following my previous question How to show an entity from in the Wirecloud MapViewer widget , I installed rush, and when I intend to start the contextBroker from the folder /etc/sysconfig I get the following results:

[root@fiware sysconfig]# contextBroker -rush localhost:1234 -https -key /etc/sysconfig/localhost.key -cert /etc/sysconfig/localhost.pem
E@19:00:10 exitFunc[1009]: unlink(/tmp/contextBroker.pid): No such file or directory
[root@fiware sysconfig]# F@19:00:10 ***[1063]: Connected to mongo at localhost:orion
E@19:00:10 restStart[764]: MHD_start_daemon failed
restStart: error 3
E@19:00:10 orionExit[998]: restStart: error

Although I get "MHD_start_daemon failed" when I check if the rush and the contextBroker are running, with the "netstat -tupln" command, I get the following result :

[root@fiware /]# netstat -tupln

And then I return to "https://mashup.lab.fi-ware.org" and I put the following input on each widget/operator:

NGSI Source

NGSI server URL: thiisorioncontextbroker:1026/ (with http no https)

NGSI proxy URL: https://ngsiproxy.lab.fi-ware.org/

NGSI entities: City

NGSI Attributes: position

NGSI Entity to Poi

Coordinates attribute: position

But nothing shows up in the map again .

After have runned the following command I got an ssl error:

[root@fiware sysconfig]# curl -k https://localhost:1026/version
curl: (35) SSL connect error

----------------------------------------------------------------------------------

I killed the contextBroker running process and start again, and then I runned the following command again:

[root@fiware sysconfig]# curl -k https://localhost:1026/version
<orion>
<version>0.14.0</version>
<uptime>0 d, 0 h, 15 m, 18 s</uptime>
<git_hash>5e3d210e4b15fa9ebbfa07c93dd41f8b41697d0e</git_hash>
<compile_time>nodate</compile_time>
<compiled_by>fermin</compiled_by>
<compiled_in>centollo</compiled_in>
</orion>

The contextBroker url with https protocol (https://YYY.YYY.YYY.YYY:1026) works perfectly with NGSIUpdater widget. So I'm also using in the wirecloud widget/operator https://YYY.YYY.YYY.YYY:1026 instead of http://YYY.YYY.YYY.YYY:1026, but I still don't get the marks (PoI) to be shown in the MapViewer.

Running netstat -tupln again show me the following results:
