Error message when asking for Indexation in Google search console

Site URL: https://www.horizon-centreparamedical.fr/

Hello,

I am a french user 🙂 so I will translate Google term in english from french version!

I am trying to index my URL : https://www.horizon-centreparamedical.fr/

But when I click 'Ask for an indexation' a loading screen appears and then show me an error message like "A problem occurred while sending your indexing request. Please try again later."

Can someone helps me ?

Thanks for your time,

Julien
