Apify SDK Proxy Errors: Causes & Fixes

Apify SDK manages proxy configuration and rotation for actors. In Apify SDK, you set the proxy endpoint (host:port), choose HTTP/HTTPS or SOCKS5, and add username/password credentials or allowlist your server IP.

Overview

Setting up Apify SDK Proxy Errors takes three things: the proxy host and port, working credentials or an IP allowlist, and a quick test that proves your requests use the proxy. Apify SDK (JavaScript) is a scraping framework. Apify SDK manages proxy configuration and rotation for actors. In Apify SDK, you set the proxy endpoint (host:port), choose HTTP/HTTPS or SOCKS5, and add username/password credentials or allowlist your server IP.

Configuring Proxies in Apify SDK

In Apify SDK, you set the proxy endpoint (host:port), choose HTTP/HTTPS or SOCKS5, and add username/password credentials or allowlist your server IP.

  • Category: Scraping framework · Language: JavaScript.
  • Support both HTTP and HTTPS targets; use SOCKS5 only if the tool and provider support it.
  • Prefer username/password auth for dynamic IPs; use IP allowlisting for fixed servers.
  • Test Apify SDK against an IP-echo endpoint to confirm traffic actually routes through the proxy.
  • Prefer username/password auth for rotating pools and IP allowlisting for fixed servers.

Apify SDK Proxy Errors and Fixes

  • 407 Proxy Authentication Required (wrong or missing credentials) — check credentials, protocol, and that the proxy IP is active.
  • SSL/TLS certificate errors when tunnelling HTTPS through the proxy — check credentials, protocol, and that the proxy IP is active.
  • Connection timeouts from a dead or overloaded proxy IP — check credentials, protocol, and that the proxy IP is active.
  • 403/429 responses when the target detects the proxy or rate — check credentials, protocol, and that the proxy IP is active.

HTTP, HTTPS, and SOCKS5

Most work in Apify SDK Proxy Errors 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.

Adding Rotation

To rotate within Apify SDK Proxy Errors, either use a provider gateway that changes IP per request, or cycle a list of endpoints yourself. Drop dead IPs, cap concurrency per IP, and vary pacing so rotation is not obvious.

Frequently Asked Questions

How do I set a proxy in Apify SDK?

In Apify SDK, 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 Apify SDK?

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.

How should I test proxies for Apify SDK Proxy Errors?

Run a small batch against the real target, measure success rate and latency, confirm the IP geolocates correctly, and watch bandwidth. Never judge a provider from a single request.

Do I need residential proxies for Apify SDK Proxy Errors?

Not always. Residential or mobile IPs are safer for protected sites, social platforms, and commerce targets; datacenter IPs can be enough for simple, public pages where speed matters more than stealth.
