The next step is to delete (or rename) the NSManagedTasks.xml file in C:\ProgramData\NVIDIA Corporation\NetService\. Note that it’s in the ProgramData folder, not the Program Files (x86) folder. You may need to show hidden folders in order to see it.
Once NSManagedTasks.xml is deleted or renamed, open Task Manager, click the button to Show processes from all users, then end the NVNetworkService.exe *32process.
Now that the process is ended, go back to Services, right-click on the NVIDIA Network Service and start it.
Exit GeForce Experience if it’s running, and start it up again. It should now be able to connect.
