Portable git with proxy: SSL certificate problem: unable to get local issuer certificate

Hello,

I know this question has been asked many times across the developer community, but I can’t get my git to run on my Windows computer.

On this computer, the internet will be accessed with a proxy server. I successfully configured that with http.proxy.
As I have no admin rights on this pc I wanted to use a portable version of git. So I am using cmder for my terminal and for git access now.

After configuring the proxy server I wanted to clone a private repo from gitlab.
But as soon as I want to clone it, the following error message appears and git exits the command:

fatal: unable to access ‘https://gitlab.com/averi/admin-panel.git/’: SSL certificate problem: unable to get local issuer certificate

I searched through a lot of topics on google and tried everything that seemed right. i.e. https://blogs.msdn.microsoft.com/phkelley/2014/01/20/adding-a-corporate-or-self-signed-certificate-authority-to-git-exes-store/.

I tried to copy the .cert from the /usr/ssl path, also from the mingw32 path, added the root certificate, as described in the link above, but nothing worked.

If it helps, here is my git config list:
