我无法连接到websockets。 1883端口工作正常。 这是MQTT.fx的输出：

我对服务器和端口进行了Telnet测试，得到一个空白终端。 我想这意味着有一个连接，否则我会有一个＆＃34;连接失败＆＃34;。消息日志插件没有显示任何内容，日志文件中没有任何内容。
其Debian和HiveMQ 3.2.2。

好吧，这是一个Nginx问题，因为没有SSL，我的JavaScript网站就可以运行。 对于websockets，应该可以使用SSL作为http而无需使用SSL，我可以在这里看到：
我尝试了配置，但没有运气。
解决方案： 使用HiveMQ不需要Nginx代理。 问题是Firefox不接受websockets的自签名证书。设置＆＃34; network.websocket.allowInsecureFromHTTPS＆＃34;真实将使它工作。在Chrome中，您会收到有关JavaScript安全性的消息，您可以接受它。由于我只使用Firefox而且没有消息，因此需要花费数小时才能找出问题所在。 paho onFailure功能也没有显示出来。
