Error installing library in ubuntu

[mateusxxlima]

Hello, I want to use jsonschema in my TCC project, but I'm having some problems

When I run the command sudo luarocks install jsonschema I get the following error

Installing https://luarocks.org/jsonschema-0.9.9-0.src.rock
Missing dependencies for jsonschema 0.9.9-0:
   net-url (not installed)
   lrexlib-pcre == 2.9.1-1 (not installed)

jsonschema 0.9.9-0 depends on net-url (not installed)
Installing https://luarocks.org/net-url-1.2-1.rockspec
Cloning into 'neturl'...
fatal: unable to connect to github.com:
github.com[0: 20.201.28.151]: errno=Connection timed out


Error: Failed installing dependency: https://luarocks.org/net-url-1.2-1.rockspec - Failed cloning git repository.

But everything is fine with git and github on my machine

when I use the --verbose flag I can see that luarocks is using git:// instead of https://

os.execute: 	cd '/tmp/luarocks_net-url-1.2-1-BrL1dz' && 'git' 'clone' '--branch=v1.2-1' '--depth=1' 'git://github.com/golgote/neturl.git' 'neturl'
Cloning into 'neturl'...

I've already run the command git config --global url."https://github.com/".insteadOf git://github.com/, but it doesn't work

Thanks if anyone help me
