I have a VM on our LAN with Ubuntu 20.04 and Zammad Community installed and working.我在我们的 LAN 上有一个虚拟机，安装了 Ubuntu 20.04 和 Zammad 社区并正常工作。 We use Synology Application Portal (Reverse-Proxy using nginx) to access it from outside and this is working too.我们使用 Synology Application Portal（使用 nginx 的反向代理）从外部访问它，这也有效。

But a functionnality of Zammad is Livechat and uses Websockets to work and, that's the snag, Websockets doesn't work, Chat will not initialize on our main website (hosted outside).但是 Zammad 的一个功能是 Livechat 并使用 Websockets 来工作，这就是问题所在，Websockets 不起作用，Chat 不会在我们的主网站（托管在外部）上初始化。

Here is the error in javascript console on the website while loading the livechat:这是加载实时聊天时网站上javascript 控制台中的错误：

1 个解决方案

The solution is to enable Websocket communication on the Synology Application Portal entry by adding some custom headers.解决方案是通过添加一些自定义标头在 Synology 应用程序门户条目上启用 Websocket 通信。

In the DSM, open the Control Panel under "Application Portal" tab在 DSM 中，打开“应用程序门户”选项卡下的控制面板
Select the app you want to enable Websockets Select 要启用 Websockets 的应用程序
Go to "Custom Headers" tab Go 到“自定义标题”选项卡
Add theese two entries:添加这两个条目：
"Upgrade" with value "$http_upgrade"值为“$http_upgrade”的“升级”
"Connection" with value "$connection_upgrade"值为“$connection_upgrade”的“连接”
