### Describe the Bug

Connection to Cursor server failed: [wsl exec: installServerScript] Command failed with exit code 4294967295: stdout: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.  
Error code: Wsl/Service/0x8007274c

### Steps to Reproduce

open Cursor IDE, wait.

### Operating System

Windows 10/11

### Version Information

Sometimes - I can sometimes use Cursor

This seems to be related to running docker containers.

Hey, thanks for the report. Error `0x8007274c` is a Windows socket timeout. The WSL process stops responding, and Cursor can’t reach its server. The Docker connection you mentioned is a good clue, since Docker Desktop and WSL together can quietly hit resource limits.

Try these steps in order:

1. In PowerShell, run `wsl --shutdown`, then reopen Cursor
2. Create or edit `C:\Users\<username>\.wslconfig` to increase resource limits:

```auto
[wsl2]
memory=8GB
processors=4

```

Then restart WSL with `wsl --shutdown`. This is especially important if you run Docker containers at the same time as Cursor.
3. Update WSL: `wsl --update`
4. Inside WSL, remove Cursor’s server files: `rm -rf ~/.cursor-server`, then reconnect from Cursor

A couple questions to narrow it down:

- Which WSL distro are you using?
- How many Docker containers are usually running when this happens?
- What does `wsl --version` show in PowerShell?

A similar issue is described here: [Cursor fails after some time when using WSL](https://forum.cursor.com/t/cursor-fails-after-some-time-when-using-wsl/151877)

Let me know if any of these steps helped.

Thank you for your answer @deanrie.  
I have followed your steps and for now it seems stable again.

I additionally updated and cleaned up my docker. Removed images, containers etc.

I use only one container at the same time.

my wsl version:

also the –update did not install a newer version:

I am running ubuntu wsl version 2:

and I am not on the latest ubuntu, I could/should update that:
