Version preview alias URL returns "Page not found"

I'm trying to deploy a fully static site and support automatically creating preview URLs for PRs (manually rather than using the Git integration), but I'm having issues getting the alias URL to work. When uploading a new version, the Version Preview URL works just fine, but Version Preview Alias URL just returns the standard "There is nothing here yet" 404 page.

Would this have anything to do with why my github PRs don't have the "Preview URL" in the comment? The preview URL is in the CF build logs.
