Where does the bug appear (feature/product)? Cursor IDE Describe the Bug Cursor Agent consistently gets stuck at “Planning next moves” and eventually fails with ERROR_EXTENSION_HOST_TIMEOUT. The Agent execution provider does not respond within the deadline, even though Cursor’s built-in Network Di…

I think I found another important clue on my system. I checked Git because the cursor-retrieval extension appears to call which git and then spawn Git processes. On my Apple Silicon Mac I had two Git installations: which git → /usr/local/bin/git file /usr/local/bin/git → Mach-O 64-bit executable…

Facing same issue. agents are stuck on planning next moves, also Git functionalities does not work, unable to see changed files etc. Agents are totally unusable. This is after upgrading to MacOS 27. Cursor Version 3.20.21.

having the same issue. SSH connection to remote servers failed within cursor too. although in my case, all network diagnostic passes.

Thanks for sharing this. I checked the SSH issue on my system as well. I’m running: macOS 27.0 Apple Silicon Cursor 3.20.21 However, on my system: which ssh → /usr/bin/ssh file /usr/bin/ssh → Mach-O universal binary, arm64e And /usr/local/bin/ssh does not exist: /usr/local/bin/ssh …

Hey all, thanks for the reports, and @Siyuan_Feng for the digging. A few different things are landing here after the macOS 27 update: Agent stalls / Agents Window times out but Network Diagnostics pass ( @urbanx , @Siyuan_Feng ): it’s timing out locally before anything reaches us, so it’s not your set…

@mohitjain its the Authentication UI, a cursor tab and Agent Endpoint. DNS/HTTP/SSL are loading indefinitely. DNS is already to 1.1.1.1 and Local Network is enabled for Cursor. Did restart multiple times. To me the login never happn [Screenshot 2026-09-17 at 07.59.53]

So, the git issue is solved with config update. Thanks for that. Regarding the agent stuck issue, its happening both on IDE and agent window for me. it’s not timing out. just this showing message forever. it’s been more than 1hr of waiting, still same issue. [Screenshot 2026-09-17 at 4.57.22 PM]
