Failed to check registry.npmjs.org for updates: "timeout of 10000ms exceeded" 
Hi! 
I kept on getting the above error on my logs whenever I went to the plugins page of the Homebridge UI, and when I go to install a plugin, even on the terminal. There was this other post which suggested going to virtual machine (i'm running the server on windows) and doing as follows:

However, the file will not save as the 'file or directory does not exist.'
How can i fix it?
