Linaro stock rootfs image cannot be downloaded now, in build-rootfs-img.sh

[Aningsk]

I was using scripts/build-docker-img.sh script to generate the Docker image.
This script calls scripts/utils/build-rootfs-img.sh , which tries to download the Linaro stock rootfs image via wget :
https://snapshots.linaro.org/member-builds/qcomlt/testimages/arm64/1379/initramfs-tiny-image-qemuarm64-20230321073831-1379.rootfs.ext4.gz

However, the download fails :

Connecting to snapshots.linaro.org (snapshots.linaro.org)|34.252.32.115|:443... failed: Connection timed out.
Giving up.

Could someone please check if this rootfs image is still available on snapshots.linaro.org?
Alternatively, is there a way to build this rootfs image from source by myself?
Thanks!
