I can easily access *.png or *

Answer 1

I just found the cause of the issue in my cpanel who give me this 404 on mp4 problem maybe is useful for someone, the file manager v3 happen to change the first character of the name of ".mp4" to a capital letter, so i get back and change my html and it works.
