First check OpenAI's official supported-country page and service status, then save the exact error shown. Access can also be affected by the account, browser, device, network path, or a temporary outage.
IPOK can show recent hosting, proxy, VPN, blocklist, registration-country, and neighboring-range evidence for the current IP. It cannot see OpenAI's internal decision or turn correlation into a confirmed cause.
Regional support is publicly checkable. IPOK shows a dated 2026-08-20 snapshot, but you should still verify the official page before an important use.
If a page returns Cloudflare 1020, that only establishes that the site's Cloudflare security rule denied the request. The code does not reveal the exact trigger or prove anything about account status.
Account, device, browser, request behavior, and service status may also matter. OpenAI's full internal rules are not public, and IPOK does not claim to reconstruct them.
IPOK can show whether third-party sources label the IP as hosting, proxy, VPN, Tor, or blocklisted, plus registration, geolocation, and neighboring-range context.
It cannot observe the ChatGPT account, device fingerprint, browser challenge, payment details, request behavior, or server-side policy, so it cannot name the decisive signal.
A normal compliant home, mobile, or office connection can be used as a comparison. A residential label still does not guarantee access.
Before blaming OpenAI, inspect region, datacenter vs residential, native vs broadcast, risk-source details, and the /24 neighborhood, then run WebRTC manually. WebRTC contacts public STUN, while candidates are parsed locally and never sent to IPOK.
IP classifications and reputation scores only narrow the investigation. Paid, residential, native, or low-risk labels are not proof of platform access. Save the error, check official status and regional support, then compare account, browser, and network factors one at a time.
Regional support is only one condition. Account, browser, device, network path, and temporary service state may also matter. IPOK can only inspect IP-side signals.
No. It means a site Cloudflare rule denied that request, but the code alone does not reveal the trigger or account state.
No. It summarizes IP-layer evidence returned by third parties and excludes account, device, behavior, and OpenAI's internal policy.
