Failed to compile Linux kernel release 16.3 for WP76xx

I used to be able to compile the linux kernel release 16.3 for WP76xx a few months ago. Today I attempted to build it again, but the build failed with error:

ERROR: lz4-native-1_1.7.4-r0 do_fetch: Fetcher failure for URL: ‘git://github.com/lz4/lz4.git’. Unable to fetch URL from any source.
ERROR: lz4-native-1_1.7.4-r0 do_fetch: Function failed: base_do_fetch
ERROR: Logfile of failure stored in: /home/vboxuser/workspace/linux-distro/yocto/build_bin/tmp/work/x86_64-linux/lz4-native/1_1.7.4-r0/temp/log.do_fetch.11819
ERROR: Task (virtual:native:/home/vboxuser/workspace/linux-distro/yocto/poky/meta/recipes-support/lz4/lz4_1.7.4.bb:do_fetch) failed with exit code ‘1’

Any idea of what is wrong here. Thanks.

does this help?

Thanks. The solution we found out is similar:
