Netlify "Page not found" when refreshing or opening a link

What it means in plain English

Same cause as on Vercel: your app is a single HTML page that handles routes in the browser, but Netlify looks for a real file at each path.

Likely causes

• No _redirects file or netlify.toml redirect.
• The _redirects file isn't in the published folder (e.g. it's not copied into dist).

How to fix it, step by step

1. Create public/_redirects (Vite copies public/ into dist/) containing:

/*  /index.html  200

2. Or in netlify.toml:

[[redirects]]
  from = "/*"
  to = "/index.html"
  status = 200

3. Make this the last rule if you have others. Real files still win, so assets keep loading.
4. Commit and redeploy.

How to check it worked

• Open a deep link directly and refresh; it should load.
• In the deploy summary, Netlify should list 1+ redirect rules processed.
