Whenever I choose the models from OpenAI or Claude, Cursor always reminds me: This model is not available in your region. However, I’m in Japan. This area is clearly within the available region range. I can directly use the Claude/ChatGPT app without any problem. Why doesn’t it work in Cursor? May I ask, how does Cursor determine my location based on which information? Why did this misjudgment occur? If these excellent models aren’t available for me to use, then why should I still pay you the subscription fee?

Hey, Japan is a supported region for both OpenAI and Anthropic, so this shouldn’t happen under normal conditions. A few things to check:
Are you using a VPN or proxy? Cursor determines your region based on your IP address. If your traffic routes through a restricted country, like China, models from those providers will be blocked even if you’re physically in Japan.
Try running network diagnostics: Cursor Settings > Network > Run Diagnostics. This will help us see what’s going on with your connection.
As a quick workaround, try selecting Auto mode. It should automatically pick an available model.
If you’re not using any VPN or proxy, share the diagnostics results and I’ll look into this further. It’s possible your IP is being misidentified.
I can see what’s happening. In the SSL logs I see IP: 127.0.0.1, which means your traffic is going through a local proxy. That’s what’s causing the issue.
Cursor checks your region by IP on the server side. Even if ipinfo.io shows a Japan IP, Cursor might see a different exit IP, depending on how your proxy routes traffic. If that exit IP resolves to China, OpenAI and Claude models will be blocked.
What to do:
Fully disable any proxy or VPN like Clash, Shadowsocks, V2Ray, etc, including the system proxy
Restart Cursor
Try selecting the model again
If it works without the proxy, then it’s a routing issue. In that case, set up your proxy so traffic to *.cursor.sh and *.cursor.com goes direct by adding them to your bypass list, or make sure your exit IP does not resolve to China.
