### Describe the Bug Connection lost, see title I can’t get any connection to cursor it seems. it just times out over and over again. ### Steps to Reproduce Just type anything into the terminal to the agent. I’ve been getting the same error message since about an hour after midnight last night (11hrs now) here in Stockholmregion. This happent once before. Cursors page says everything is up, but clearly it’s not. This might be a case that the DNS problems from last night are NOT fixed everywhere for some reason ### Expected Behavior No timeout, get an answer back… ### Operating System Windows 10/11 ### Current Cursor Version (Menu → About Cursor → Copy) Version: 1.2.4 (user setup) VSCode Version: 1.99.3 Commit: a8e95743c5268be73767c46944a71f4465d05c90 Date: 2025-07-10T17:09:01.383Z Electron: 34.5.1 Chromium: 132.0.6834.210 Node.js: 20.19.0 V8: 13.2.152.41-electron.0 OS: Windows\_NT x64 10.0.26100 ### Additional Information Restarted computer multiple times, tried with and without VPN. All other internet works fine. ### Does this stop you from using Cursor Yes - Cursor is unusable ---

The same problem. I create new chats, change VPN (without VPN doesn’t work in my country), restarted computer multiple times, disabled http2. But it doesn’t work Connection failed.

Creating a new chat worked. (changing from gemini to gpt didn’t). Quite frustrating though before you realize what’s going on. ---
