Solution

  • Your git instance has been configured to use a proxy and that proxy is failing.

    Try unsetting the environment variables, for example on Linux:

    export http_proxy=
export https_proxy=
export HTTP_PROXY=
export HTTPS_PROXY=

    Check your git config files for a proxy. Unset them with these commands:

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

    Check the vscode interface for these options (environment variables and proxy settings). Try changing the proxy options from system to none.
