Being given clone git "Failed to connect to 127.0.0.1 port 2453: Connection refused" how to deal with?

1. Check the git configuration

git config --global --list| grep -i proxy

If the content output, then the unset configuration items, such as:

git config --global --unset http.proxy

2. Check the Environment Variables

env | grep -i proxy

If the content output, then the output variable unset, the need to exit the current terminal oh

unset http_proxy
