Assignment link doesn't work (404 page not found)

[ValentinaInterdonato]

I was added to the class https://github.com/SapienzaInteractiveGraphicsCourse by my professor. I also successfully accepted an assignment
https://classroom.github.com/assignment-invitations/8850583aaff624dba3670f5de43697dd/success

but when I click on the link https://github.com/SapienzaInteractiveGraphicsCourse/ig-hw1-ValentinaInterdonato
I get a "404 page not found" message

Also, if I click on the class link I can't see any content, as if I wasn't enrolled at all
