Glitch only shows listing directory

When I click on Show Live for my project, Glitch shows only the listing directory and I need to click on the html file to see it. This problem appeared on a new project, on other project the html filed was opened directly. Can someone help please?

What is the name of the project where this is happening? The most common cause of this is removing index.html from a front-end project.

Changing the name worker!! So it was only because of the name of my html was not index that it did not work. Thank you very much!

I still don’t understand, can someone explain to me?
