Federation Error

[Giuseppe_Fiore]

I have created a federation between a Thingworx Core (customer)  & Instance Thingworx Vuforia (customer) , to connect some services on a thing into AR experience.

But not function , and into monitor Web i have this type of Message:

Refilling connections on [endpoint 477, uri: wss://xxxxxxxxxxxxxxxxxxx:443/Thingworx/WS] failed : timeout waiting for websocket handshake to complete

i have tried to connect the same Federation with a trial instance of Vuforia & this work perfectly.

Should something be activated in the Vuforia instance (customer) ? or what ?

thnx 

Giuseppe

if you follow the instructions form "TWX Federation Setup Guide.docx" is the federation working in Vuforia Thingworx instance- means step 5 is working there? 

So means is the problem in the federation on the Vuforia Thingworx instance or  the issue occurs only in Vuforia Studio?
