Fix Logi Options+ Backend Connection Problem on Windows 11
If you have just set up a new Windows 11 PC and plugged in your Logitech mouse or keyboard,
you may have encountered a frustrating message inside Logi Options+:
“Backend connection problem — click here to launch backend”
No matter how many times you click that link, the app keeps showing the same error and your
device settings remain inaccessible. The good news: this is a known Windows 11
compatibility issue with a straightforward fix that takes less than two minutes.
This guide walks you through the exact steps.
Why Does Logi Options+ Show a Backend Connection Problem?
Logi Options+ relies on a background service (LogiOptionsPlus.exe) that must
run continuously to communicate with your Logitech hardware. On Windows 11, a security feature
called Local Security Authority (LSA) Protection — part of Core Isolation —
can prevent this service from starting or connecting properly.
LSA Protection was introduced to shield Windows credential processes from malicious code.
However, it can also block legitimate third-party software services, including Logi Options+,
especially on freshly installed or recently updated Windows 11 systems.
The Fix: Disable LSA Protection in Windows Security
The most reliable solution is to turn off Local Security Authority Protection
in Windows Security. Follow these steps carefully — you will need administrator rights.
Step 1 — Open Windows Security
- Press Win + S and type Windows Security.
- Click Windows Security to open the app.
Step 2 — Go to Device Security
- In the left sidebar, click Device Security.
Step 3 — Open Core Isolation Details
- Under the Core isolation section, click Core isolation details.
Step 4 — Disable Local Security Authority Protection
- Scroll down to find Local Security Authority Protection.
- Toggle the switch to Off.
- If prompted by User Account Control (UAC), click Yes.
Step 5 — Restart Your PC
- Windows will ask you to restart to apply the change. Click Restart now.
- After restarting, open Logi Options+.
- Your Logitech devices should now appear and be fully configurable.
The full navigation path is:
Windows Security → Device Security → Core isolation → Core isolation details →
Local Security Authority Protection → Off
Alternative Solutions If the Problem Persists
If disabling LSA Protection alone does not resolve the issue, try these additional steps:
Reinstall Logi Options+
- Go to Settings → Apps → Installed apps.
- Find Logi Options+ and click Uninstall.
- Download the latest version from
Logitech’s official website. - Install and relaunch.
Run Logi Options+ as Administrator
- Right-click the Logi Options+ shortcut or executable.
- Select Run as administrator.
Check the Background Service
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Services tab.
- Look for LogiOptionsPlus — if it is stopped, right-click and select
Start.
Update Windows 11
Go to Settings → Windows Update and install all pending updates.
Microsoft periodically releases patches that improve compatibility with third-party software.

that the LogiOptionsPlus service is running in Task Manager. Updating Windows 11 to the latest
version can also help.
Conclusion
The “Backend connection problem” in Logi Options+ is almost always caused by
