VIZIO's apps article works in order. Check the TV's internet connection: Menu, Network, Test Connection, and read the result; reconnect to wifi if needed. If connected but the app still fails, restart the modem and router, check whether other apps work, test the same app on a phone or computer, move the TV and router closer and try a phone hotspot to see whether the home network is at fault. If only one app fails, the service or account may be the cause.
The checks in more detail
If the app shows an error code, write it down or photograph it and search the provider's site or status page for an outage. Power cycle the TV by unplugging it for five seconds, or use Menu, Reset & Admin, Soft Power Cycle where the model has it (some models label the menu Help or System). Check the scope: if other apps work, the problem is that app, its service or your account, so confirm the login and sign out and back in;
if several apps fail, recheck the network and power cycle. As a last step, factory reset: Menu, Admin & Privacy, Reset to Factory Settings, which erases settings, network information and app logins, so you must set the TV up again. VIZIO's app management article covers finding, adding and managing apps, and its airplay and casting articles cover apps that support them. Update the TV under Check for Updates.
Writing down the error code before you restart anything matters because a restart clears the message and the code is what the provider's support pages are indexed by. Try the app on a phone on the same wifi; if it fails there too, the service or account is the cause. If you have more than one streaming device, test the same app on another one on the same network; if it works there, the fault is the TV rather than the network or account.
