git works fine for a direct connection to the internet. However problems occur when using behind a proxy/firewall. Utilizing https:// would help alleviate this problem. HTTPS uses port 443 which is very rarely blocked or restricted by firewalls/proxies.
I have just ran the script on my Pi3 behind a proxy. With the old revision I got a connection refused error from github, with https it has gone straight through.
