Why and how to fix this?
This happens because you are missing an index.html on the directory you are accessing.
For examples: - If this happens on your home page, which means you are missing an index.html on your Publish directory.
- If this happens on the subdirectory of your site, for example,
/blog, this means your site doesn’t include an index.html on that subdirectory e.g.,/blog/index.html.
Custom 404 Pages
If you want to create a custom 404 page for your site, just create an index.html file and put it under <your-publish-directory>/404/index.html.
