Set the proxy in the operating system, then prove the app really follows it with a one-minute test.
OpenAI's network guidance for ChatGPT lists the domains the web and app need, asks that TLS inspection does not break the app or its long-lived WebSocket connection, and describes a "Network configuration issue" alert on the macOS app that comes from SSL inspection on the network. It gives no proxy settings screen for the desktop app.
That is why this page tests instead of promising. A proxy also changes only the address the service sees: it does not change what ChatGPT allows in a country, and the exit should be in a country OpenAI supports and where you actually are.
Open Settings, then Network & internet, then Proxy.
Under Manual proxy setup, next to Use a proxy server, choose Set up and turn the switch on.
Enter the host in Proxy IP address and the port in Port, leave the intranet-addresses option ticked, and Save. Use an HTTP asset: Microsoft's page describes one server entry and does not mention SOCKS.
Restart the ChatGPT app and run the wrong-port test below.
Open the Apple menu, System Settings, then Network. Select the service you use (Wi-Fi or Ethernet) and click Details, then Proxies.
Turn on Web proxy (HTTP) and Secure web proxy (HTTPS) and enter the same host and port in both. SOCKS proxy is a separate switch for a SOCKS5 asset.
Switch on Proxy server requires password and enter the user name and password from My assets. Apple's page offers this option for the web, secure web and SOCKS proxies.
Click OK and Apply, restart the ChatGPT app, then run the test below.
Change the proxy port to a wrong number, for example one digit off, and save.
Restart the ChatGPT app and send a message.
If it stops loading or shows a network error, the app uses the system proxy: put the correct port back. If it works normally, the app ignores the system proxy: use ChatGPT in a browser with the proxy set there.
| Item | Windows | macOS |
|---|---|---|
| Where | Settings, Network & internet, Proxy | System Settings, Network, Details, Proxies |
| Proxy types on the screen | One manual server entry; SOCKS not mentioned | Web (HTTP), Secure web (HTTPS), SOCKS, PAC URL |
| User name and password | No field on the page | Proxy server requires password option |
| Proxy302 asset to use | HTTP (port 2222) | HTTP (port 2222) or SOCKS5 (port 3333) |
Windows and macOS steps from the Microsoft and Apple support pages, read 14 November 2026. Ports from the Proxy302 product facts file.
Check Check host and port, then the protocol: an HTTP asset needs the HTTP entry, a SOCKS5 asset the SOCKS entry (macOS only).
Fix Switch to an HTTP asset on Windows, or correct the entry.
Stop when If a browser loads sites through the same proxy but the app does not, stop and use the browser.
Check On Windows there is no place to enter a proxy user name and password; browsers show a prompt, other programs may simply fail.
Fix Run a local forwarder that holds the login, and point Windows at 127.0.0.1 and its port with no password.
Stop when Do not type the password into the address field.
Check OpenAI links this alert to SSL inspection or decryption on the network, for example a security tool in the path.
Fix Update the app, switch off the inspecting tool for OpenAI domains, or use ChatGPT in a browser meanwhile.
Stop when If a policy requires inspection, contact OpenAI support.
Check OpenAI notes that proxies and firewalls must allow the WebSocket upgrade to chatgpt.com on TCP 443.
Fix Test the same proxy in a browser; if that works, the app path is the problem.
Stop when Do not switch exits repeatedly while testing.
Check Check whether the computer can open the proxy host and port.
Fix Open Proxy302 Fast Connect and click 「一键加速」, then retry.
Stop when Only for users already in mainland China.
For an account you sign in to every day, a static ISP IP keeps the exit the same for the whole lease: US$0.50 for 1 day, US$7.99 for 30 days, HTTP on port 2222 or SOCKS5 on port 3333 chosen at purchase. The AI-subscription ISP page explains the GPT / Grok tier made for ChatGPT. Auto-renew is optional and can be switched off per IP; there is no free trial.
If you only want ChatGPT in a browser, the Proxy302 Chrome extension sets the proxy for that browser alone and leaves the rest of the computer untouched.
OpenAI's network guidance describes none. Set the system proxy and run the wrong-port test to see whether the app follows it.
The system proxy applies to every program that reads it. For one site only, use a browser with a proxy extension; a per-app tool needs third-party software we do not cover here.
HTTP works on both systems. SOCKS has its own entry only on macOS; the Windows dialog Microsoft describes does not mention it.
No. It only changes the address OpenAI sees. Use an exit in a supported country where you actually are.
Only if a firewall or proxy filters traffic: OpenAI lists the domains, and asks for WebSocket upgrades to chatgpt.com on TCP 443 to be allowed.
Set a proxy for ChatGPT in a browser, in the macOS and Windows apps and on iPhone and Android over Wi-Fi, and check the exit IP.
Compare your country with the official list, check the exit IP type, align WebRTC, DNS, language and time zone, then keep one steady address.
Use Proxy302 from mainland China: download the free Fast Connect 2.3, click 「一键加速」 (One-click boost), and fill in your proxy details exactly as given.
Install the Proxy302 browser extension in Chrome, Edge or 360 Browser, send a proxy from My assets with one click and check your exit IP. HTTP proxies only.
Fixed static ISP proxies: a residential-grade IP that stays the same for the whole term. For social accounts, stores and AI tools. HTTP and SOCKS5.
