Probably a super easy question about "index.html"

Hi, This is probably stupid, but I am uploading a website and it only works with “index.html” typed in (which isthe sites file), is there any way to get it to work just by going to “”?
it has been uploaded to the sites root folder[hr]

ok it automatically updated after 10 minutes

That’s how things normally work, unless you did something weird to defeat it. A file called index.html will be displayed automatically from the URL of the raw domain name.
