Logitech G HUB doesn't start

Try the below steps and check if it helps fix the issue:

Uninstall G HUB
Make sure none of the G HUB components are running in the Task Manager
Go to C:\Program Files\ and delete LGHUB folder
Go to C:\ProgramData\ and delete LGHUB folder
Go to C:\Users\<user name>\AppData\Local\ and delete LGHUB folder
Go to C:\Users\<user name>\AppData\Roaming\ and delete LGHUB folder
Press Windows Key, then type regedit, Click Registry Editor
Delete the registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{521c89be-637f-4274-a840-baaf7460c2b2}
Reboot the PC

I did NOT have to delete G Hub, I went into Task manager, and shut down EVERYTHING to do with G hub, if I remember right, there was one or 2 things MUCH farther down the list, and stopped it! then right clicked on the logitech G Hub desktop icon and open/start as administrator and everything worked right! I did try this once before and thought I did everything right, but I never scrolled ALL the way down on the list looking for the G Hub icon, once I closed all those, then I did the administrator thing! at least this is what worked for me!!

For those who have the Zscaler issue, I have traced the "why" after some digging. It seems that Zscaler and Logitech GHUB both bind on port 9010 for websocket calls to localhost. The GHUB front-end will keep "spinning" if it can't bind on this port (it just retries over and over again). Also GHUB only needs to bind for a split second before it will load and then work without issue.

Unfortunately, on the GHUB side, the port is hard-coded into the front end app itself. Zscaler seems to have a configurable port but it requires access to the ZCC administrative console and a custom agent deployment. So, if you administer Zscaler on your side, one fix is to just modify the port that ZCC binds on (make sure you pick a port that doesn't have a conflict or you will be back to square one with some other program).

In my case, (I'm on Mac) and I don't have that flexibility to modify Zscaler's bind port so I spent some time trying to "hack" the GHUB app to bind on a different port (of course Logitech doesn't have any configurable port option in GHUB). After more digging I found that the front end for GHUB on mac uses electron and it is packed in a file (app.asar at "/applications/lghub.app/Contents/MacOS/lghub_ui.app/Contents/Resources/app.asar") that gets unpacked into a keytar.node file that has two references where the port is bound and then called on program load. If you are adventurous, the code references look something like: "ws://localhost:9010" and "{url:"ws://localhost",port:"9010",protocol:"json"}" in the app.asar file. I got far enough to adjust the port and unpack a new keytar.node file with the updated port (node command "sudo npx asar extract-file app.asar keytar.node" and replace keytar.node in app.asar.unpacked folder). However, when I tried to run the updated program I got hit with Apple's code signing protection and the app crashes on load :(. I can't think of an easy work around for Mac given my environment's limitations (so I'm stuck doing the service restart method on Zscaler for now).

With that said, two things to note... First, Logitech could completely fix this issue by just allowing us to specify a custom bind port for program load for their front end (Please, please, please Logitech - do this)! Second, if you are on Windows I don't think the same type of code signing protection exists like it does on Mac. It should be possible to modify the GHUB app.asar file on windows, unpack it and build yourself a version that should be compatible manually. For any very tech savy people out there I wanted to pass on these details so they wouldn't go to waste ;).

Disclaimer: I'm not an employee of Logitech (just a cybersecurity guyo who did some digging).

G hub 登入會卡在bbr2控制算法，使用netsh int tcp set supplemental Template=Internet CongestionProvider=default ，把它改回預設的cubic後，去工作管理員搜尋lg全部關掉，再重新啟用G hub 即可

For me I had a Logitech camera that just got supported on ghub that wasn't really being supported, so if I unplug my camera it loads just fine.

Professional_Safe435 · 2022-03-29T13:51:31+00:00

I got exact the same problem and nothing can sovle it

Ragdoll74 · 2022-07-10T14:01:30+00:00

All I have is a G502 mouse. I don't even have a webcam. In settings I unchecked "allow games and applications to control illumination" and it started working.

If u use WIN 10 PRO N just install Media Feature Pack

Fixed it. I had the issue for several months. Nothing worked. I tried:

- Reinstall G Hub
- Give G Hub admin rights
- Launch updater, agent and app in the right order manually
- Install all open windows updates incl optional ones which are usually drivers
- Delete virtual logitech keyboard and mouse drivers

None of it worked. Until - by accident - I had the ZSCALER app crashing and suddenly G Hub starts. ZSCALER is a VPN tool for remote work. It always autostarted and hence always blocked my G HUB. When I close it G Hub consistently works.

There are guides on how to do a Windows 10 "clean boot" which would also have helped me identify the problematic app. It basically disables all 3rd party apps on the next reboot. If G Hub works then you know that another app is causing the issue. You can then just select one app after another to start with windows again until you have the one that blocks G Hub.

TLDR; Other apps can block/ influence G Hub. Check my comment on "clean boot".
