First identify whether the TV has no signal, the box cannot reach the internet, or only one app fails. For no signal, verify the selected HDMI input and cable. For a network issue, compare another device on the same connection.
What to check
Restart the box normally, verify date and time, and retry the affected app. If one app alone fails, record its name and error text. Avoid a factory reset until support has assessed the situation; it may remove settings and apps.
Contact support with the model and a photo of the error. Use legitimate application sources. A server-side outage is not proof that the hardware needs replacement.
