git error report and solution inventory

Error One

fatal: unable to access'https://github.com/.......git/': Failed to connect to github. com port 443: Timed out

Solution One

1. Check your git configuration

git config --global -l

If you don’t have any content related to https proxy, such as https_proxy=…, the problem is not here. If you have content related to https proxy, please delete it from the ~/.gitconfig file and try again

1. If it still doesn’t work, please unset the environment variable

env|grep -i proxy

You should have one or a few lines https_proxy = … use the following to unset them one by one: unset https_proxy (or HTTPS_PROXY, depending on the name of the variable)

1. Check the environment variables again

env|grep -i proxy

If it doesn’t show anything you should be good. Note: This solution can be applied to http and https proxy issues. Just change the variable name from https to http

Solution Two

1. Manually configure the git proxy. The git client can enter the following two commands

git config --global http.proxy http://127.0.0.1:1080
git config --global https.proxy http://127.0.0.1:1080

1. Cancel proxy

git config --global --unset http.proxy
git config --global --unset https.proxy
