404 eroor message on SIRIL site for Pratical Cases in reference to Cyril Richard Book

Hello,
I have purchased the book on astrophotography, mastering image processing with Siril by Cyril Richard. In the book, there is a reference to a site on Siril.us to download practical cases in order to perform the same demonstration in the book. However, entering the HTTPs address produces a 404 error, could someone for the SIRIL team fix the broken link?
Kind Regards
MICAM

For me it works

Thank-you, I am now able to download the files. There is a missing «/» in the site address in the book.

The last “/” is not needed. Practical cases | Siril also works.
