> +Question:+
> Data retrieval from Orion Context broker subscription fails
> +Description:+
> with a successful subscription in orion context broker, a listening accumulator server fails to recieve any data, under any circumstances I can find to test.
> We are using an ubuntu virtual machine that has a nested virtual machine with Fiware-orion in it. Having subscribed to orion context broker and confirmed that it was successful by checking the database and also having confirmed that data is successfully updated, the accumulator server fails to respond.  unable to tell if this is a failure to send from orion, or to receive by accumulator, and unsure how to check and continue, we humbly beg the wisdom of the stack overflow community.
> We have run the accumulator server on both virtual machine on the same PC and on another PC with non-vm ubuntu. The script we are using to subscribe is presented below:
> Orion VM
