韵律mod_bosh：Session中有1个请求打开，send_buffer中有0个

Question

我正在尝试jitsi-meet。环境是debian 7 + nginx +韵律（包括jitsi-videobridge组件）。

在我启动nginx，韵律和jitsi-videobridge之后，韵律调试日志是：

我尝试了不同的解决方案：

1. consider_bosh_secure = true;，并使用https
2. The authentication is already set to "anonymous"
3. set timeout to 120s

但它们都不起作用。我不知道there are 0 things in the send_buffer的可能原因是什么。我想在我的设置中可能是错误的端口配置。

任何有助于解决问题的想法都将受到高度赞赏。
