由于代理设置，Jabber登录失败

简介

本文档介绍Cisco Jabber登录失败的原因，原因是工作站上定义了代理。 

先决条件

要求

Cisco 建议您了解以下主题：

• 思科统一即时消息和在线状态(IM&P)
• 思科统一通信管理器 (CUCM)
• Cisco Jabber客户端
    

使用的组件

本文档中的信息基于以下软件和硬件版本：

• 用于Windows 11.8的Cisco Jabber
• 思科网络安全设备(WSA)9.1
• CUCM 11.5
• IM&P 11.5

问题

定义系统代理时，Cisco Jabber登录失败，不允许流量到达呼叫管理器下载其配置。

解决方案 1

您可以将客户端配置为绕过代理，并直接转到代理设置例外部分的Call Manager;导航至“控制面板”>“网络和互联网”> Internet选项> 连接> LAN设置> 高级

您可以按星号(*)定义例外，然后按域、单个IP地址或范围定义例外；例如*.MY.Domain;192.168.1.1;192.168.1.12-14 的多播地址发送一次邻居消息。

解决方案 2

配置代理以重定向来自Jabber客户端的流量以重定向到适当的Call Manager。

解决方案 3

从Windows客户端删除代理配置，然后让Jabber的HTTP GET方法绕过代理和来自PC的所有其他流量。这取决于从客户端到Call Manager的网络流，如果介于之间的基础设施通过Web缓存通信协议(WCCP)发送Web流量，则该流量将无效。

验证

检查工作站上的代理设置。 

步骤1.从命令行检验代理配置；导航至命令提示符并运行命令netsh winhttp show proxy

步骤2.您可以导航至“控制面板”>“网络和Internet”>“Internet选项”>“连接”>“LAN设置”。

• 没有代理时：

• 当存在代理时：

步骤3.运行命令"regedit"并导航到HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Internet Settings

• 未定义代理时： 
  
  

• 定义代理时：
