Disney+
Disney+ reports problems with short numeric codes, and two dominate on TVs: error 83 ("Something went wrong" — a device compatibility, connection, or account issue) and error 42 (trouble connecting to the internet). Both usually respond to a restart, an app update, or a network check rather than anything on Disney's side.
