I am trying to clone a GitHub project in my office system.

```
set HTTPS_PROXY=http://<UN>:<PWD>@<PROXYSERVER>:<PORT>
set HTTP_PROXY=http://<UN>:<PWD>@<PROXYSERVER>:<PORT>

```

I have set HTTPS and HTTP proxies also set sslVerify to false

```
[https]
    sslVerify = false
[http]
    sslVerify = false

```

still, I am getting "Unknown SSL protocol error in connection to github.com:443".

Can someone advise me what do I need to do?
