I am trying to clone the angular-phonecat git repository, but I am getting the following message when I enter the command in my Git Bash:
$ git clone git://github.com/angular/angular-phonecat.git
Cloning into 'angular-phonecat'...
fatal: unable to connect to github.com:
github.com[0: 204.232.175.90]: errno=No error
You can try to clone using the HTTPS protocol. Terminal command:
git clone https://github.com/RestKit/RestKit.git
Open port 9418 on your firewall - it's a custom port that Git uses to communicate on and it's often not open on a corporate or private firewall.
You can make git replace the protocol for you
git config --global url."https://".insteadOf git://
See more at SO Bower install using only https?
I had the same error because I was using proxy. As the answer is given but in case you are using proxy then please set your proxy first using these commands:
git config --global http.proxy http://proxy_username:proxy_password@proxy_ip:port
git config --global https.proxy https://proxy_username:proxy_password@proxy_ip:port
