Does this stop you from using Cursor

Yes - Cursor is unusable

and I already tried this

Please try this:

  • Start a new chat (don’t continue the old one). This error is often tied to a corrupted session state.

  • Instead of Auto, pick a specific model (for example, Claude Sonnet 4.6). We’ve seen cases where Auto fails but a specific model works.

  • If that doesn’t help, try Ctrl+Shift+P > “Clear Editor History” and then restart Cursor. and it doesn’t work. :frowning:

嘿 M3WAVER,我觉得问题出在你运行的 Cursor 版本太旧了!2.6.21 版本已经过时了,至少从那之后出过一次大更新!你可以按照截图里的指引更新你的 Cursor 应用程序:)

thanks for replying, when I updated as ur suggestion, this error message popped up"Connection failed due to proxy setting error",then I downloaded the latest version to overwrite the current one. But it still doesn’t work.

for this error, you can try doing this and see if the issue persist :

thank you Tom!!! when I set it to HTTP/2 and it finally worked, could you help me explain it?

Glad this fixed your issue, well.. to see the actual reason, I would need more detail from your network and potentially look at the logs, but usually it’s just a http version issue that is not in term with the current network! Enjoy your time using Cursor!
