Does Versailles Royal Opera sell last-minute concert tickets?

I'd like to go to a concert in Versailles but there are no tickets left to buy on the website. I know a lot of venues sometimes do sell extra tickets on the day of event, so I'm wondering if it's worth trying going to Versailles that day and getting that tickets. Does anyone know is it's possible?

If not, I'd rather visit Versailles on a different day.
