Ive had a chat with the tech teams and this is what they've said about Error 3-
It means that TV connected to the console is not HDCP compliant or the console lost the secure connection over HDMI.
If that happens mid-stream, it is probably because the TV was switched off and the console lost the secure connection.
Other reasons can be caused by AV receivers, soundbars etc. that sit between the console and the TV.”
Hope this helps!
