The container fails to build the wireguard package (at least over here).

Description
I have built the synobuild image, but when I invoke this command: "sudo docker run --rm --privileged --env PACKAGE_ARCH=geminilake --env DSM_VER=7.2 -v $(pwd)/artifacts:/result_spk synobuild", I get the error below:

Steps to reproduce
Even when I run the command manually on my NAS:

wget https://git.zx2c4.com/wireguard-linux-compat/snapshot/wireguard-linux-compat-1.0.20220627.tar.xz

I get a file that's exactly "81260" bytes in size, and it doesn't untar properly.

When I tried downloading this file from my Windows PC via Firefox by simply entering the URL, it consistently requires several attempts before the file can eventually be downloaded. And the size of the file is actually "264016" bytes in size.

Expected behavior
The container can complete this step wget https://git.zx2c4.com/wireguard-linux-compat/snapshot/wireguard-linux-compat-1.0.20220627.tar.xz

---

I actually have a local copy of the file because I can get Firefox to download it albeit with failed attempts before it can successfully be donwloaded. Can anyone tell me how to work around this problem and build an image that grabs this file elsewhere when the step is reached (so I can feed the file to the container instead of it trying to get the file from https://git.zx2c4.com/wireguard-linux-compat/snapshot/wireguard-linux-compat-1.0.20220627.tar.xz)?

Update: Finally compiled successfully with a workaround (that's only possible as I happen to run a web server myself).

Both
https://git.zx2c4.com/wireguard-linux-compat/snapshot/wireguard-linux-compat-1.0.20220627.tar.x
and
https://git.zx2c4.com/wireguard-tools/snapshot/wireguard-tools-1.0.20210914.tar.xz

Simply cannot be downloaded successfully by the container. I even tried with the container behind a VPN provider to mimic connecting from various countries, but no good. There is clearly a problem currently with git.zx2c4.com from what I can tell.

Like I said, I could download these two files successfully with a desktop browser and after making numerous failed attempts. So I ended up hosting these 2 files in my own file server, then change the "Makefile" to change the URL from git.zx2c4.com to myownserver.com, before building the image then creating the container to make the .spk installation file.

But the problem remains that git.zx2c4.com seems to be super unstable.
