Cursor IDE

Describe the Bug

Can’t initiate a conversation with any model

Steps to Reproduce

Connected to Windows for Arm (Parallels) using OpenSSH for Windows. Tried to run cursor with cursor --disable-extensions but still nothing works.

Something to mention, I had to increase the Remote.SSH: Connect Timeout time from 30s to 120s in order to complete the installation of cursor-server on the VM.

I’m on Windows and I’m experiencing a v similar issue. I’ve been using a custom LLM and it just suddenly stopped working around 2:30AM (UK) on 1 Jan 2026. Using any other models provided under the Cursor subscription don’t work either…

I left the application and re-opened to find the below whenever I add a prompt:

Only solution was to roll back to version 2.2.44. This was a recommendation from forum.

Vojkan_Dobrosavljevi · January 3, 2026, 7:12pm

This helps…Thanks

Des_Donnelly · January 3, 2026, 7:12pm

Hi Dean Rie.. greetings from Ireland and Happy New Year.. I’m using it since Aug 2025 and do not have/use Git because the permissions are too permissive for my liking.. there was never any issue using Agent without Git but now in last 48 hours I have same issue as the OP “The agent execution provider did not respond within 4 seconds. This may indicate the extension host is not running or is unresponsive.” - so it will simply not work for me?

If you are on Windows, this should now be fixed. might need to restart Cursor to pick up the change!

noor · January 4, 2026, 4:48am

Fixes for Linux and macOS are on the way.

kolaedr · January 14, 2026, 10:31am

Every day there are some updates but on Mac the same error and the chat (agent) does not work(

kolaedr · January 14, 2026, 11:20am

MacOS solution (not recommended, but works)

Close Cursor.
Press Cmd + Shift + G (Go to Folder) in Finder.
Type ~/Library/Application Support/Cursor/.
Find the User folder and rename it, for example, to User_backup (so you can restore it).
Launch Cursor. It will ask you to log in as a “clean” user.

Yes, you will start with a clean slate (lost chat history but can restore it if needed) but it works!

solidusex · January 14, 2026, 3:49pm

I also rename ~/Library/Application Support/Cursor to Cursor.bak.
re open cursor ,log in and exit.
copy Cursor.bak/User/Settings.json && KeyBinding.json.
delete Cursor.bak.

maybe some one find Cursor/Settings file, we can backup it.

noor · January 15, 2026, 12:37am

this is a long thread so I just want to double check the exact problem you are running into. are you experiencing the “Agent Execution Timed Out Error”? Can I also get the output of your Cursor > About Cursor?

silentCoder · January 15, 2026, 3:34pm

Guys - the issue persists for >2 weeks. Unable to use agents. Please fix that.

In the mean time - going back to VScode.

noor · January 19, 2026, 1:24am

hi @silentCoder. can I get some more information about your setup? Cursor version, platform, remote SSH or not, etc. we recently bumped the timeout for agent execution requests from 4 to 16 seconds to help with higher latency.
