I thought from the main Reservations thread that one could use ‘ Interrail.eu/Eurail.com reservation service (+ 2 EUR/train booking fee - reservation included)’ for Italy-Austria-Germany. This is for 2 November.
But I cannot get there - when I log into interrail.eu, it says:
The train is included in your Pass but also requires a supplement. You can buy it online, at the station, or on board the train.’ and sends me here:

It also says re reservations: ‘ No price results were found. Pass holder reservations may be sold out for this connection, but there are other ways to check for available seats—more info below our timetable. ’
