I bought an interrail global pass to travel. For some parts of my trip I need seat reservations.
However I get faced with an error that blocks me from reserving my seat.

It is specific for the train from Montpellier Saint-Roch to Brussels on September 18th, departure at 2:52 PM. When I try to add the seat reservation to the cart this error pops up: “WE CAN NOT MAKE YOUR RESERVATION. The train you found in the timetable has changed recently. Please choose another connection.”

I’ve been trying to wait to see if it got solved over time. However it’s know the third day and it’s not solved
