Since this was posted in the IDE 2.x category, I assume that you are using IDE 2. The library you are referring to is 5 years old and made before IDE 2.x became available.
It would probably be far easier to use the Library Manager in IDE 2 to install the libraries that you require. Just click the book icon on the left hand side of the IDE window and type the name of the actual library that you need in the search box. Find that library you need from the list and click the Install button.
Have you already installed those dependencies? If you have, then you don't need to do anything else. You already have everything that you need. If you have downloaded but not yet installed, then just install the required libraries via the Library Manager.

This error looks like a process on the internet for your IDE session seemed to stop working as you were installing the .ZIP library. The IPV6 (2606:4700::6812:a15) maps to CLOUDFLARE in SF, CA, USA, which has recently been part of internet outages worldwide. Maybe it saw the zip file as malicious.
Try again. I just installed the zip file successfully...
