You get this message when the system is behind a firewall and when the security certificates are blocked.

There are two ways to overcome this message and to enable a git pull or git clone.

i) Issue the below command from git bash

$ git config –global http.sslVerify false

OR

ii) Add http block in “gitconfig” file to avoid ssl verification

[http]
sslVerify = false
sslCAinfo = /bin/curl-ca-bundle.crt
