Flights not being tracked (Eurowings / LGW)



i’m wondering why this flight is not being tracked:

It’s in the air right now at 1500Z as EWG9222 with mode-s code 3C4A23

Just had

come by just before not being tracked as well.
mode-s code was 3C4A2C i believe.

Also tried searching by registration but nothing different came up.
