@prakashsinhab Can you download http://downloads.webmproject.org/releases/webp/libwebp-0.4.3.tar.gz ?

[pubaayaam]

I could download the file.

Now what all should I be doing with it?

The simplest solution is to look into the problem by yourself, instead of just hurrying the maintainers.

Probably this issue was fixed in the upstream project. https://github.com/request/tunnel-agent/pull/15

@prakashsinhab Feel free to comment more if the problem still occurs even though you use the latest cwebp-bin.
