Addressing NVIDIA Software Connection Failure in OS X

GeForce Experience is a handy app for gaming optimization. However, some GeForce Experience users have posted on NVIDIA’s forum about the “unable to connect to NVIDIA” error message. Those users see that message when they start GeForce Experience.

GeForce Experience still opens when the “unable to connect to NVIDIA” error occurs. However, users can’t download NVIDIA drivers or utilize other features like ShadowPlay in that software because of this error. As such, here is how you can fix the “unable to connect to NVIDIA” error in Windows 11 and 10.

1. Erase the NSManagedTasks.xml and Restart the NVIDIA Network Service

Users with older GeForce Experience versions have been able to fix the “Unable to connect to NVIDIA” error by deleting an NSManagedTasks.xml file. However, that file doesn’t exist for more recent GeForce Experience versions. So, not all users will be able to apply this potential fix.

If you’re utilizing older GeForce Experience software, you might be able to resolve this issue by erasing the NSManagedTasks.xml file like this:

1. To view File Explorer, pressWin + E .
2. ClickView >Show >Hidden Items in Windows 11 File Explorer. In Windows 10 File Explorer, you’ll need to select theHidden Items checkbox on theView tab.
   
3. Clear the current folder path in File Explorer’s address bar. Then input this NetService folder path and hitEnter :
   C:\ProgramData\Nvidia Corporation\NetService\
   
4. InputNSManagedTasks.xml in Explorer’s search box to find that file within the folder.
   
5. Right-click theNSManagedTasks.xml file and select itsDelete option (the trash can in Windows 11).

Once that’s done, it’s time to restart the NVIDIA network service.

1. Bring up the Task Manager tool, which has a usefulCtrl +Shift +Esc hotkey for quick access.
2. Select Task Manager’sDetails tab.
3. Then find and select theNvStreamNetworkService.exe (NVIDIA Network Service) there.
