Overview
Use cURL to quickly test proxies, verify IP changes, and debug authentication issues.
Examples
HTTP proxy with auth
curl -x http://USER:PASS@HOST:PORT https://api.ipify.orgSOCKS5 proxy (proxy DNS too)
curl --proxy socks5h://USER:PASS@HOST:PORT https://api.ipify.orgTroubleshooting
- If you see SSL errors: try updating curl or add --tlsv1.2 (temporary)
- If 407: credentials are wrong or auth is required
- If connection refused: wrong port or proxy not reachable
Pro Tip
Always test your proxy with api.ipify.org before integrating into an app.
