Good news , glad it was of some help,
Sky need to sort the issue,
Looking at the way Sky Go connects to both Skyq box and several anayltics and AWS sites, SkyQ conenctions keeps trying to send and re-open the same port (4730) on skyq box ( this fails and eventuallys triggers soem buffering) , it all seems to overwhelm the box, and then drops its network ocnnection , and drops the analysics conenctions to sites like
a92-123-199-218.deploy.static.akamaitechnologies.com:https
and sky amazon servers
ec2-52-49-100-189.eu-west-1.compute.amazonaws.com:https ESTABLISHED
This is clearly a SKY issue, nothing to do with our own network conections ( LAN or WAN connections) ,
so sky need to take ownership and fix this.
