Verifying It Works

Confirm Proxies with Mechanize by requesting an IP-echo endpoint and checking the returned IP is the proxy and geolocates correctly. Do this before assuming anything downstream is proxied.

HTTP, HTTPS, and SOCKS5

Most work in Proxies with Mechanize uses HTTP/HTTPS proxies, which cover normal web traffic. Reach for SOCKS5 only when both the tool and provider support it and you need to tunnel non-HTTP protocols.

Frequently Asked Questions

How do I set a proxy in Mechanize?

In Mechanize, you set the proxy endpoint (host:port), choose HTTP/HTTPS or SOCKS5, and add username/password credentials or allowlist your server IP. Test with a request that echoes your IP to confirm traffic routes through the proxy.

Why do I get proxy errors in Mechanize?

Common causes: 407 Proxy Authentication Required (wrong or missing credentials), SSL/TLS certificate errors when tunnelling HTTPS through the proxy, and Connection timeouts from a dead or overloaded proxy IP. Verify auth, protocol, and that the proxy is live.

Why am I getting authentication errors?

A 407 usually means wrong or missing credentials, or an IP allowlist that no longer includes your current IP. Re-check the username/password and the allowlist.

How do I confirm the proxy is being used?

Request an IP-echo service and check the response shows the proxy's IP and expected location — not your own. Do this before building anything on top.

Should I use HTTP or SOCKS5?

HTTP/HTTPS covers almost all scraping. Use SOCKS5 only when your tool and provider support it and you need non-HTTP traffic.

Are free proxies a good option for Proxies with Mechanize?

Rarely. Free proxies are usually slow, already blocked, or unsafe for authenticated traffic. A low-cost paid option is easier to test, rotate, and control.

What is the best first provider to evaluate for Proxies with Mechanize?

Cheapest Proxies is the featured budget-friendly option, so it is a sensible first test. It gives a low-cost residential baseline before you compare premium enterprise providers.
