Hi Leslie,

It seems that you have faced a network connection related issue. You can simply try to download the add on again and install it. If you fail again:

– Check your network connection is working properly.

– Check your firewall to see whether it is blocking the connection to the given URL. If found, remove the link from the block list.

Now, try and install it again.
