@Crolee   Hi, could we have a bit more information please.  You are not talking to Sky we are just customers like yourself trying to help each other.  How long have you had Sky Stream and was it working ok previously and just gone to a grey screen or is this your first time of setting it up?

Would suggest first trying a restart of your Sky Stream box
Go to Settings>Systems Management>Resets & Updates
Select Restart device
Your Sky Stream puck will perform a reboot. It will take a few minutes to complete.

To check your speed is the minimum required for Sky Stream, can you do a network speed test on each of your Pucks.

Sky recommended minimum broadband speed is 25Mbps. Or 30Mbps if you add an extra Sky Stream puck or to watch in UHD.
To run the test launch Netflix on your pucks (you do not need to be logged into it, if you do not use netflix) and scroll down the left menu to Get help.
Choose Check Network.
Would suggest running the test a few times, say a few minutes between tests.
What is your speed?
