Cannot install neovim via asdf ref:master

after running the command

asdf install neovim ref:master

The build starts happening. and then I see

[ 47%] Generating usr/lib/luarocks/rocks-5.1/mpack

Error: Error fetching file: Failed downloading - failed downloading
make[3]: *** [usr/lib/luarocks/rocks-5.1/mpack] Error 1
make[2]: *** [CMakeFiles/mpack.dir/all] Error 2
make[1]: *** [all] Error 2
make: *** [deps] Error 2

This is recurring issue and is not solved by reinstalling neovim by asdf.
How to install neovim via asdf?

It sounds like an Internet problem.
