git 操作出現 "error: while accessing https://github.com/xxx/xxx fatal: HTTP request failed"

os centos 6.x
git 1.7.1

git clone, git pull 都會出現下面的訊息

# git clone https://github.com/git/git.git
Initialized empty Git repository in /usr/local/src/xmrig/git/.git/
error: while accessing https://github.com/git/git.git/info/refs

fatal: HTTP request failed

google 之後大概都是下面的解法
# git config --system http.sslVerify false

還是不行的話、可以先嘗試更新相關程式
# yum update -y nss openssl ca-certificates


reference:CentOS 6 git clone SSL connect error
