404 error

I don’t see a 404 error, I only see a 403 error. And the 403 error is caused by the fact that you website doesn’t have any index file.

Looking at what you do have, you appear to have dumped the source code of a React site in your account. While you can host a React site with us, we do not have the facilities to build the TypeScript source code into actual web content.

So please npm build your site locally first, and then upload the built web pages to our hosting to make your site work.
