Frequently Asked Questions

Why is a proxy marked operational, but target websites still block my requests?

Liveness only guarantees the TCP socket accepted a handshake. Major platforms actively inspect ASN types (datacenter IPs are heavily flagged), DNS leakage, TLS client fingerprinting, and blacklists.

What separates Elite, Anonymous, and Transparent proxies?

Elite proxies strip all proxy-identifying headers so target servers see you as a normal direct visitor. Anonymous hides your IP but admits proxy routing. Transparent forwards your true client IP in headers like X-Forwarded-For.

What causes a Connection Timeout?

A timeout indicates the proxy did not answer within the allocated window (e.g. 8s). This usually stems from physical distance, server overload, or an IP whitelist on the proxy rejecting our probe source.
