Recently, many users in China have reported that they are unable to use Cursor, especially with the Claude series models, which have all been disabled.
This issue is likely known to everyone.
The reason is that model providers like OpenAI, Google, and Anthropic have explicitly stated that they do not provide services to mainland China, resulting in Cursor being unable to access the relevant models.
This is an upstream issue and not something Cursor wants to disable.
So how can we solve this?
In recent days, I have seen the most forwarded solution is to change HTTP to 1.0.
This can only temporarily downgrade the issue.
Why do I say it’s a downgrade?
Please see the explanation from the Cursor official website; Cursor’s AI functionality relies on HTTP/2.
Therefore, many users who switched to 1.0, including myself, frequently encounter connection failures.
It can be very frustrating when the connection fails unexpectedly.
So how can we completely resolve this issue?
I saw a method shared by a master, Zhao Shifu, which is very effective, and I want to share it with everyone.
The method is quite simple, but many people say it still doesn’t work, so I will explain it with images and text.
The method is as follows:
Step 1: Choose a node in the United States or Japan;
Step 2: Install service management
This does not directly enable TUN mode, but you need to install the service first.
I am using Clash, as shown in the image below:
Step 3: Enable TUN mode
If Cursor is open, you need to restart it,
and then you can freely use the Claude 4 series models.
