+You might host your pattern lab in an environment that doesn't acknowledge the default file to be `index.html` in case that none is provided – Gitlab Pages is an example for this, where you might publish your preview builds to during development. So in case that you get a URL like `<PATH>/index.html`, it will redirect to `<PATH>/?p=all`. You might not be able to share this resulting URL or even do a refresh of the page, as the server would respond with a 404 error.
