itch.io

hi do you know how to fix the problem where it says "failed to find index.html" when uploading something? I use clickteam fusion 2.5 to make my games. When i used the .exe file to upload it, it said it was a virus. So i switched the file type to html. When i upload it in here, it says this: "failed to find index.html" and i even put the html in a zip folder. What do i do?
