Hey, I see a screenshot of the “All set! Feel free to return to Cursor” page, but the client is still stuck on Log In. This usually happens for 2 reasons: the cursor:// protocol handler isn’t working, or the client’s traffic is blocked by a proxy or HTTP/2. Try this:

  1. Check the protocol handler:

    • Paste this into your browser address bar: cursor://anysphere.cursor/test
    • You should see an “Open Cursor?” prompt and the app should focus. If nothing happens, reinstall Cursor using the latest installer and run it once as Run as administrator, then launch it normally and try logging in again.

  2. Proxy for the client itself:

    • In Cursor open Settings Ctrl+,, search for proxy
    • Http: Proxy, set your local proxy address, for example http://127.0.0.1:7890
    • Http: Proxy Support, turn it on

  3. If it still won’t log in, in Settings search for HTTP/2 and enable Disable HTTP/2, or in settings.json set “cursor.general.disableHttp2”: true.

  4. Retry the login: click Log In in the client, complete the steps in the browser, then return to the client.

If it still doesn’t help, please send:

  • What happened when you tested cursor://

Let me know how it goes.

Thanks for your help;
In fact, when I input cursor://anysphere.cursor/tes Afterwards, it was indeed possible to open the corsur client. But when I click on the software interface and press Ctrl+on the keyboard, there is no response from the software interface and I cannot enter the settings interface.
