git clone can't resolve proxy

Seems the problem is reported in the mailing list. Does this help?

git config --global --unset http.proxy

Run the below command in git bash

git config --global --unset http.proxy

Note: Don't forget to restart the git bash, otherwise it won't work.

Also make sure to remove HTTPS_PROXY and HTTP_PROXY environment variables.

If the above steps didn't work for you, try setting your companies proxy as shown below;

git config --global  http://example.com:8080
git config --global  https://example.com:8080

**change example.com/8080 with your companies proxy and port

I just got the same issue, when pushing behind a firewall.

The problem wasn't an empty http_proxy var (git var -l didn't show any proxy variable), and my OS environment variables included:

http_proxy=username:[email protected]:port
https_proxy=username:[email protected]:port
no_proxy=.company

This setting would always trigger a:

error: Couldn't resolve proxy '(null)' while accessing https://...

However, as soon I changed the proxy variables, adding an 'http://' in front of the proxy addresses, the error message stopped:

http_proxy=http://username:[email protected]:port
https_proxy=http://username:[email protected]:port
no_proxy=.company

(note the 'http://' even for the https proxy address)
