1、首先找到本机内的hosts文件，打开计算机，依次展开：C:WindowsSystem32driversetc
2、在hosts文件上单击右键，选择打开方式记事本 ，打开后将里面的内容全部清空，输入下面代码：
# 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
3、更改完Hosts文件然后找到网络连接，然后找到当前使用的网络连接(本地连接)然后右键选择属性，然后找到标记的协议。
4、把DNS更改为公网DNS，这里推荐3个，分别是：
百度DNS：服务器地址：180.76.76.76 它的特点是云解析，提供云防护，无劫持，更精准的服务。
阿里DNS：服务器地址：223.5.5.5 和 223.6.6.6 它的特点是稳定，快速，智能
114DNS：服务器地址：114.114.114.114 它的特点是高速，稳定，可靠，无劫持
5、最后重置网络协议，重置完成后重启一次计算机即可正常运行LOL 从而彻底解决登录时遇到了一个预期之外的错误。
