+## Node.js 17+: ECONNREFUSED issue with IPv6 and localhost ([#705](https://github.com/chimurai/http-proxy-middleware/issues/705))
+
+Node.js 17+ no longer prefers IPv4 over IPv6 for DNS lookups.
+E.g. It's **not** guaranteed that `localhost` will be resolved to `127.0.0.1` – it might just as well be `::1` (or some other IP address).
+
+If your target server only accepts IPv4 connections, trying to proxy to `localhost` will fail if resolved to `::1` (IPv6).
+
+Ways to solve it:
+
+- Change `target: "http://localhost"` to `target: "http://127.0.0.1"` (IPv4).
+- Change the target server to (also) accept IPv6 connections.
+- Add this flag when running `node`: `node index.js --dns-result-order=ipv4first`. (Not recommended.)
+
+> Note: There’s a thing called [Happy Eyeballs](https://en.wikipedia.org/wiki/Happy_Eyeballs) which means connecting to both IPv4 and IPv6 in parallel, which Node.js doesn’t have, but explains why for example `curl` can connect.
