It's an inventory issue on Trenitalia's side, it may be the rate you are trying to book, I'm not sure what date you are searching for
but it happens to Operations also in Italiarail, we are not advised by Trenitalia how many seats are left at any rate, we must go through the
whole process and wait to see if its available, Very Frustrating I agree. Have you tried a different fare?
