【Git】fatal: unable to access ‘http://gitlab.example.com/root/test_gitlab.git/‘: Could not resolve ho

After configuring gitlab for Ubuntu16, try to access the gitlab official website through a browser and create an

error. How to solve it?
If http://gitlab.example.com is not configured, you only need to change gitlab.example.com to the corresponding ip address.

git clone http://192.168.xxx.xxx/root/test_gitlab.git
