Why Is My IP Blocked or Flagged by ChatGPT?

ChatGPT access failures may involve regional support, IP type or shared-exit reputation, as well as account, browser, device, network-path, or service-state factors. IPOK only provides a recent IP-risk snapshot and cannot identify the actual block reason; freshness follows the result and privacy-page cache policy.

Beyond regional availability, access may also be affected by edge-security and account-level signals; the exact rules are not public. IPOK can only show recent IP-side risk indicators.

Why ChatGPT is Extremely Picky About IPs

OpenAI publishes supported regions, while its complete site-security, account, device, and behavior rules are not public. Cloudflare 1020 only means that a site security rule denied the request; it does not reveal the trigger or account state.

Key Metrics to Check in IPOK

Review these indicators with the tool below: (1) IP type; (2) the recent multi-source risk snapshot, subject to the displayed cache freshness; and (3) whether registered country matches geo-routing. Treat the result as diagnostic evidence, not a guarantee of platform access.

FAQ

Why can a paid VPN still fail on ChatGPT?

Payment does not determine the exit IP's type or reputation. Hosting, sharing, or blocklist labels are useful clues, but IPOK cannot confirm that one caused this failure.

What does Cloudflare Error 1020 establish?

It means a site Cloudflare security rule denied the request. The code alone does not identify the trigger or prove the account state. A compliant network comparison may help, but residential access is not guaranteed.
