Error Code 8003 - NOT 80003

When I open my DirectTV app on my iPad Pro (IOS 15.6), I get a window that says ‘Looks like something went wrong.  Give it a try later.  (Error 8003)’.  However, I can stream with other apps with no problems.  I have made certain that my log-in is accurate, tried deleting the app and reinstalling, rebooting my iPad and chatting with tech support.  Every time I get the same error code.
