Describe the Bug

When starting to connect to wsl using wsl plugin, I get following error.
It started with an update, without changing any settings or plugins.
Its announcing “Setting up WSL Distro: Ubuntu-24.4 and then hangs in there a bit and throws and error. Seems the problem is in installing cursor-server. When doeing clean install on my coworkers computer, it works, but even if I uninstall cursor and remove left over folders, the problem persists when reinstalling.

Yes - Cursor is unusable

I’ve the exact same thing. I tried everything. I uninstalled and reinstalled the previous Cursor version 1.4.2. I uninstalled wsl and reinstall it. I also tried the previous WSL extension from Anysphere 1.08 and 1.09. Nothing works

I have the same problem

add:
The issue was resolved by additionally installing the Ubuntu 24.04.1 LTS environment.

Hi, can you share details? I had Ubuntu24.04 and I also tried another distro Ubuntu 22.04 but it had the same error.

after which Cursor successfully connected

Unfortunately it did not work for me.

12

After installing Ubuntu, did you launch it to go through the initial user initialization script?

14

Yes, I did. 24.04 was the one I initially was able to work with, until the bug appeared, then I tried with 22.04, which I initialized to check if the problem was about the distro, but it was not. I planned the wsl setup with cursor for the whole team, but clearly if one update can destroy it all, this is not an option.

Hello,
After spending my weekend debug the ■■■■■ out of this. I finally found a way to fix this.

The reason:
In a perfect world wsl will be able forward it’s 127.0.0.1 interface from linux guest to the localhost interface on windows host. In this case it cannot. From where I searched, this error happened on and off for many people for like … 6 centuries and MS has failed to fix it.

The fix:
There’s 2 script you need to run.

First, the cursor-server run on wsl with this option
cursor-server --start-server --host=127.0.0.1. We need it to run with –host=0.0.0.0 so it listen on all interfaces.
For this. You can do it manually or I wrote a script to patch the main.js of the anysphere wsl extension which exits at

C:\Users\your_username\.cursor\extensions\anysphere.remote-wsl-1.0.11\dist\main.js

you only need to run this script once, or if you update the extension run it again. All it does is search for the phrase –host=127.0.0.1 and replace it with –host=0.0.0.0

this script receive the path to main.js file of the extension. You run it like this:

patch_wsl_ext.ps1 C:\Users\your_username\.cursor\extensions\anysphere.remote-wsl-1.0.11\dist\main.js

patch_wsl_ext.ps1

Second script is to forward the cursor-server listening port from wsl to host computer.
When cursor-server run it save the listening port to its log file at
$HOME/.cursor-server/.9455eaa4c87f2bad91eda3f2bc9b42b16eae1080.log

this script read that file and run the command to forward the port from wsl → host nat ip to localhost on your windows computer. This is the command if you wonder.

netsh interface portproxy add v4tov4 listenport=$port listenaddress=127.0.0.1 connectport=$port connectaddress=$wslIp"

Forward-CursorServer.ps1

Thanks a lot, this worked for me. I adjusted the cursor server host. Did not even run the second script, as I had deleted the .cursor-server folder earlier. Had issues at first, but after wsl shutdown and new start, I was able to connect to wsl again :slight_smile:
