Yesterday i accidentally pressed the update on Cursor, after that, the connection started to fail everytime.
What should I do to make it work again?

Have you tried the solutions suggestd in this thread: Can't connect to WSL anymore - #3 by deanrie ?

Hi @HC1,

I looked into the errors in your logs. Two separate things are going on:

1. “Failed to patch code.sh launcher” (ENOENT) — This is a known cosmetic error. It does not cause your connection failure. Cursor still connects to WSL successfully even when this appears. You can safely ignore it.

2. The actual connection failure — The Wsl/Service/E_UNEXPECTED and 0x8007274c errors in your logs point to WSL itself becoming unstable, not a Cursor bug. This is usually caused by Windows updates or WSL resource exhaustion.

Quick fix:

  1. Open PowerShell and run wsl --shutdown

  2. Wait a few seconds, then reopen your WSL workspace in Cursor

If that doesn’t resolve it:

  • Check if you have mirrored networking enabled in your .wslconfig file (usually at C:\Users\<username>\.wslconfig). If networkingMode=mirrored is set, try temporarily commenting it out and restarting WSL. We’ve identified that mirrored networking can cause connection timeouts with recent Cursor updates.

  • If you need mirrored networking, try adding this to your Cursor settings (Ctrl+Shift+P > “Preferences: Open Settings (JSON)”):

    “remote.WSL.serverListenAddress”: “0.0.0.0”

To prevent recurrence, you can add resource limits to your .wslconfig:

[wsl2]
memory=8GB
processors=4

A related thread with more context: Cursor won’t connect WSL Ubuntu

Let me know if any of those steps help, or if the issue persists after trying them.
