I have an ongoing unchanged active subscription but today all the devices (glass and puck) have stopped discovery plus app working

it will load to a something went wrong screen. Have done all the reboots on sell devices and app and still doesn't work

Not sure with your last sentence, what exactly you have done.

Try a settings restart first 

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

Do an apps refresh;

1. Press Home on your Sky remote, then select Settings
2. Press System management then Resets and updates and finally Refresh apps.
3. You'll see a message that says, 'Your apps are being refreshed'.
4. Press Dismiss to return to normal viewing. 
   The refresh can take 24 hours to complete.

Login to you Discovery + account on a web browser or via the Discovery + app on a phone/tablet.

Go to Account > Manage Devices and remove the devices there you are having trouble with.

Allow a few hours for the devices to be removed, before trying to sign in again on your Sky Stream boxes.
