If you see an ITV error code on your screen, try the following steps:
Check if there is a problem with your internet connection or router. Then, restart both and see if that solves the issue.
Check for any software updates available for your device and install them if necessary.
Delete the ITV app and re-install it for a fresh start.
Check if the ITV service is down or experiencing technical difficulties.
Contact your ISP provider to see if they have any advice about the situation.
Contact ITV’s customer support team for further assistance if all else fails.
