ChatGPT doesn't receive my login / verification code?

Usually an unstable connection or a risk-controlled exit. Connect to a healthy node first, then request the code; switch nodes or retry later, and check your device clock.

Are free mirror / wrapper sites safe?

They carry account and data-leak risk; prefer the official site and assess the privacy terms yourself.

Will VLESS + Reality definitely work for ChatGPT?

No solution can guarantee access; Reality makes the handshake look like a real website to lower detection, but results depend on node quality, operations, and third-party policy.

Do I have to use sing-box?

It is not the only option, but sing-box clients have good VLESS+Reality compatibility and a consistent cross-platform experience for beginners.

ChatGPT in Iran: Regional Limits + Shared-IP Risk Control

Updated 2026-06-09

Illustration: a stable, clean international exit is the prerequisite for LLM access

Why ChatGPT often fails in Iran

In Iran many users hit “services not available in your country”, repeated login / human-verification failures, and pages or media that won't load when reaching ChatGPT and other overseas LLMs. This is usually caused by network-level filtering, regional policy, and fingerprinting of common proxy traffic — not a device fault. Heavily abused shared IPs also trigger account risk-control. For stable use you need a clean international exit that is hard to fingerprint, making traffic look like ordinary HTTPS.

ChatGPT-specific: datacenter IPs at login; route all OpenAI subdomains

Unlike Claude's per-request IP checks or Gemini's Google-account country binding, OpenAI concentrates risk control on login and verification — many users on shared exits hit captcha loops. Web and API use different hosts (openai.com, chatgpt.com, oaistatic.com); proxying only the browser tab while API subdomains go direct causes "page loads, plugin/API fails". Fix one clean exit country before chasing random node hops.

Solution: what you need

You typically need: a node service on a modern protocol (VLESS + Reality) to reduce active probing and throttling; a sing-box class client matched to your device that routes openai.com and related domains through the proxy; and a stable subscription with a reasonable data quota. Pricing and terms are on the plans page; avoid third-party top-ups. Univista offers a free quota, so you can try before buying a data pack.

Step-by-step

Copy your subscription URL from the dashboard or digital card, import it from URL or QR in the sing-box client, and update the nodes.
Pick a low-latency, healthy node (prefer a lightly loaded exit region close to Iran) and turn the connection on.
Open ChatGPT in a browser with a verified login method (per OpenAI's current policy); if the code never arrives or you hit verification loops, switch nodes and retry.
If API calls fail, check that the proxy in your terminal and environment variables matches the client.
Verify your device clock and time zone are correct to avoid TLS errors that break the connection.

Stability tips

If one node slows down or drops, switch to another before troubleshooting — same-origin nodes can be affected together.
Keep the exit region and device fingerprint stable; frequent switching is more likely to trigger account risk-control.
Exclude the client from battery optimization so the OS does not kill it in the background.
