Mingw+msys2 : Failed to connect to bitbucket.org :

I want to build ffmpeg under windows 8.1 by using this script and last version of Mingw+Msys2 , but it gets error for any hg clone from bitbucket.org , e.g:

$ hg clone https://bitbucket.org/multicoreware/x265

abort: error:Network is unreachable

After searching on the Internet I saw this page and realized it is because that bitbucket.org has IPv6 and I can not access to it . Please see results of the following commands:

$ ping -n 10 bitbucket.org

NOTE : Also, I've seen some posts on the stackoverflow.com like this. But it seems works only for Linux, Because I added 104.192.143.2 bitbucket.org to my /etc/hosts but not worked.

Please guide me.

This is not an IPv6 issue - you'd have the full [2401:1d80:1010::150] address in your ping -6 if that were the case.

Instead, it looks like you're connecting from Iran (81.12.120.0/24 is owned by an Iranian ISP). Since the US government has imposed sanctions on Iran, and since Bitbucket's infrastructure is in the US, the Bitbucket servers are required to drop requests from Iran.
