Frequently Asked Questions

How do I set a proxy in Puppeteer?

In Puppeteer, 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 Puppeteer?

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.

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.

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.

Can I use one proxy setup for every website?

No. Different sites apply different rate limits and anti-bot systems. Tune rotation, sessions, pacing, and location targeting per target.

What metrics matter most when comparing providers?

Success rate, total cost, response time, location coverage, authentication options, support speed, and refund or trial terms matter more than marketing claims.
