[Fiware-tech-help] [frontierCities2] Problem with updating the Context from IotAgent

[Maurus Frey]

Dear Fiware-Tech-Crew,

In our current setup, there is a problem with context updates from 
iotagent to the context broker (CB):

CB reports (see iota-problem.log):

	"No context element found",
	"details": "TrafficSensor:TrafficSensor01"

Checking Orion's mongodb (see Mongodb-entites.txt) the context ID seems 
to exist.

You also find the iota configuration file config.js attached 
as(Config.conf) to this email.

Why does the iotagent receive a 404-Error about the non-existing 
element? Thought the element does exist

Let me know in case you need additional log extracts or information 
about our current configuration.

Thanks for any suggestions and help. Kind regards
