Hey all, itch.io admin here. Since so many people end up on this topic when they're having errors I've written a quick guide:

1. It's very likely you've packaged your game file wrong:
   1. It must be an HTML5 game! You can not upload an .exe file and expect it to work. If you're using a game development tool it must have an HTML export option
   2. It must be a .zip file (no .rar, no .7z)
      1. You can also upload a plain .html file only if your project is fully contained in that single html file
2. If your game extracts, but is having errors:
   1. All files needed by your game must be in the zip file
   2. make sure you're using relative paths when requesting other resources
   3. filenames are case sensitive. (HelloWorld.png is not the same as helloworld.png)
   4. if you request any files on other services, HTTPS must be used

There's a more detailed guide on our docs: https://itch.io/docs/creators/html5#common-pitfalls

Please check all of these things before asking for help. Thanks

Although this topic mentions server errors, that was an isolated incident that was fixed. Downtime is very rare, and it's much more likely you're running into one of the problems described above.
