昨天公司的网络更换，然后在使用git操作代码的时候，遇见了标题所述问题。

仅以此文，记录该问题的解决过程。

首先第一步：

 得到本机的IP地址。

第二步：ping一下

 说明连接正常。

第三步：

找到git目录下的 hosts文件。

一般目录为 C:\Program Files\Git\etc

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost

在该文件下 添加 192.168.1.117 github.com

此处的IP 替换为自己的IP即可

 修改之后 如上图所示。
