Train-bubble I need your help: I want my company to buy a ticket for a sleeper train from Munich -> Warsaw

The problem: on the DB site whenever I want to book the connection it shows me the reservation is not possible and I can't book without reservation. Any idea how to check if this is a possible journey or if it's fully booked?

Fo reference the complete journey would be: 15.06.2026 15:33 Tübingen (Germany)
16.06.2026 08:00 Warsaw Central
