Frequently Asked Questions
How do I set a proxy in Python requests?
In Python requests, 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 Python requests?
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.
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.
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.
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.
How do I avoid getting blocked?
Match the proxy type to the target, rotate IPs, pace requests like a human, rotate user agents, and retry on a fresh IP after any block or CAPTCHA.
