登录时遇到了一个预期之外的错误怎么办

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。
