Ok on linux theres no problem here problem was since lately i dont know why when you close the capot and reopen system keep old clock and dont resync what i did is a systemctl restart systemd-timesyncd

Hi @Thomas_Lloancy, Thanks for the post! This matches a transient rollout issue on Windows. However, it looks like Cursor starting working for you shortly after this happened right? Let us know if you still see a similar error.

yep i have another similar Request ID: b36b336e-6553-4130-85f9-f027a0a683c2 Always-local singleton connection rejected (cold-start-timeout during ipc-ready, restartCount=6, gaveUp=true) RetriableError: Always-local singleton connection rejected (cold-start-timeout during ipc-ready, restartCount=6, gaveUp=true) at Wqi (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:9066:8640) at wcp (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:9067:11962) at Object.classify (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:9067:16467) at gdf (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:9067:5856) at async fWo.runWithSharedTurnRunner (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:9067:15819) at async xz.runAgentLoop (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:20459:3067) at async lba.streamFromAgentBackend (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:20487:14009) at async lba.getAgentStreamResponse (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:20487:23432) at async VIe.submitChatMaybeAbortCurrent (vscode-file://vscode-app/c:/Program%20Files/cursor/resources/app/out/vs/workbench/workbench.desktop.main.js:9229:2399)

Thank you! @Thomas_Lloancy This request never reached us. Something that has been working for a lot of these types of issues is this series of steps here: Unable to use Cursor Chat – "An unexpected error occurred" - #11 by kevinn Do you want to try that and lmk how it goes? If still blocked can you run Network Diagnostics in Cursor Settings and let us know what you see?

I guess that my problem is very similar: [image] Cursor services network issues since 3.9 Help Hi, since Cursor 3.9 most network services do not work anymore on Windows 11. Still the same in recent 3.11.13. When I install Cursor 3.8 most services work (not all). I have already set HTTP Compatibility Mode to HTTP/1.1. Could anybody help?
