If you are using uBlock Origin or other strict adblockers, they might aggressively block the download API servers (savenow.to and lbserver.xyz), resulting in a Network Error or xhr_failed message.

How to fix (Add an exception to uBlock Origin):

1. Click the uBlock Origin icon in your browser and open the Dashboard (⚙️ gear icon).
2. Go to the My filters tab.
3. Copy and paste the following lines at the bottom:

   @@||savenow.to^
   @@||lbserver.xyz^
   

   (Note: The @@ prefix is the specific syntax that tells uBlock to whitelist/unblock these domains).
4. Click Apply changes and refresh the YouTube page.
