Corporate Github behind proxy: Received HTTP code 503 from proxy after CONNECT : <p>I am trying to clone from a corporate git repo, but always receive this error message after a while:</p>

<p>fatal: unable to access URL: Received HTTP code 503 from proxy after CONNECT</p>

<p>I have the following .gitconfig file:</p>

<pre><code>[https]
    sslVerify = false
    proxy = https://proxy.corpadderess:8080
[http]
    sslVerify = false
    proxy = http://proxy.corpadderess:8080
