I cloned the application commcare-hq after installing python

I cloned the application commcare-hq after installing python and django in my cpanel. here's the link: GitHub - dimagi/commcare-hq: CommCareHQ is the server backend for CommCare, the world's largest platform for designing, managing, and deploying robust, offline-first, mobile applications to frontline workers worldwide but whenever i enter the following command

git submodule update --init --recursive

i get the following error

fatal: clone of 'git://github.com/dimagi/xml2json.git' into submodule path 
'/home/hcdcnetl/myProject/commcare-hq/submodules/xml2json' failed
Failed to clone 'submodules/xml2json'. Retry scheduled

For future reference this type of question should be asked in the 'Developers' category.

The issue appears to be a network issue: github.com[1: 192.30.253.112]: errno=Connection refused.
