TV-APP 00148 error

Have a brand new LG smart TV.  Xfinity Stream App was working fine until today.  I have uninstalled and reinstalled.  Logged out and logged back in.  Unplugged the television.  None of this works.

The app works fine on the phone and the computers as my roku.

Any real suggestions would be helpful.

The bot on chat did something to my service but it made no difference.

Thanks in advance
