### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug Any request to any model is resulting in a “Taking longer than expected”. I have restarted my machine, downgraded HTTP compatibility mode to HTTP/1.1 and HTTP/1.0, tried in a new blank folder and run the network diagnostics (that report some errors). Have also changed network connections but to no avail. Cursor is completely unusable right now. ### Steps to Reproduce Submit a chat request to plan or to make code changes. ### Screenshots / Screen Recordings ![Screenshot 2026-03-04 at 4.14.40 PM.png](https://us1.discourse-cdn.com/cursor1/original/3X/b/d/bda1368778ce5b75ef1892e8c6e6aee58344d057.png) ### Operating System MacOS ### Version Information Version: 2.5.26 (Universal) VSCode Version: 1.105.1 Commit: 7d96c2a03bb088ad367615e9da1a3fe20fbbc6a0 Date: 2026-02-26T04:57:56.825Z Build Type: Stable Release Track: Default Electron: 39.4.0 Chromium: 142.0.7444.265 Node.js: 22.22.0 V8: 14.2.231.22-electron.0 OS: Darwin arm64 25.3.0 ### For AI issues: which model did you use?

Hey, thanks for the report. From the diagnostics, I can see DNS, downloads, CDN, and most endpoints are OK, but Authentication fails with a “Failed to fetch” error. That’s likely the root cause. If authentication doesn’t work, all AI requests will time out. A couple questions: 1. Are you behind a corporate proxy, VPN, or firewall? That’s the most common reason why Authentication fails while other endpoints still work. 2. Can you try a different network, like a mobile hotspot, to rule out filtering on your corporate network? I also see you’re on version 2.5.26. The latest is 2.6.11. It’s worth updating since we fixed a lot of bugs. A few more things to try: - Sign out and sign back in: Cursor Settings \> sign out, then sign in again. - Grab the Request ID from a failed chat request (top-right of the chat panel \> menu \> Copy Request ID) and send it here. We need it to trace what’s happening on the backend. If you’re on a corporate network, your IT team may need to allowlist `prod.authentication.cursor.sh` and `*.cursor.sh`. Docs are here: [Network Configuration](https://cursor.com/docs/enterprise/network-configuration) Let me know what you find. ---

I tried signing out and signing in again with the current version but thats not working either. Now i am unable to sign in the app when I am authenticated on the web and can see my account details. In the app, it just remains stuck to Sign in. The update within the app is not working either. If i try to download the upgraded version from the website, it takes me to this page: [https://api2.cursor.sh/updates/download/golden/darwin-arm64/cursor/2.6](https://api2.cursor.sh/updates/download/golden/darwin-arm64/cursor/2.6) which is down currently as well. I have tried multiple internet connections including my personal non firewall/vpn one. The app was working like a breeze last night. I had two instances open and was working heavily on 2 apps at the same time. What is going on now ? ---
