I remember when one user along myself were having an issue with the classic not going to recovery mode. after changing resolution it went to recovery screen.
uninstall Disney+ app first by going to settings, apps, Disney+ and uninstall then restart your box. wait for your box to reinstall Disney+ app then relaunch and should work
then turn off your box, then restart modem and router and wait until modem/router is ready. then turn on your box and see if that helps. if not then try using vpn.
