Rustwasmc install binaryen-version_90-x86_64-linux.tar.gz failure!

This issue is similar to this issue in wasm-pack: rustwasm/wasm-pack#864
I'm confused of this download failure, how can I fix it?

It might be a firewall issue ... Are you trying this in China?

Yes! I tried it in China.
But I have tried to use github host and system proxy, it is possible to download files from ‘GitHub.com’ quickly.
Everything was OK when I used wget and curl to download file in ‘ https://github.com/WebAssembly/binaryen/releases/download/version_90/binaryen-version_90-x86_64-linux.tar.gz’.
I don’t know where this file will be used by Rustwasmc.

Rustwasmc will use wasm-opt in this file to slim the wasm file. You know, in China, it is not stable to access github, so maybe you can try several times. And if your proxy protocol is SOCKS, maybe you can try using HTTP instead.

It's very strange.
I have changed my proxy to http;
But it seemed no change when I typed rustwasmc -v --log-level=info build
I got this log still:

Try to change your ISP or connect to the 4G hotspot?

@wangshishuo Thanks for your help. I found it's my Internet problem. I tried for ten times, and succeeded in the last chance.
