websocket - 通过 Websockets 连接到 Mosquitto Broker 时出错

问题描述

当我尝试连接我的 mqtt 服务器时，在HIVEMQ上使用客户端，我收到以下错误：

Firefox can’t establish a connection to the server at ws://burooq.com:8083/mqtt.
Connect failed: AMQJS0007E Socket error:undefined.

我正在使用以下参数：

运行命令mosquitto，我得到响应：

[ 1615.745348]~DLT~ 1670~INFO     ~FIFO /tmp/dlt cannot be opened. Retrying later...
1608926628: mosquitto version 1.6.9 starting

我的 Mosquitto conf 文件是：

allow_anonymous false
password_file /etc/mosquitto/passwd

listener 1883 localhost

listener 8883
certfile /etc/letsencrypt/live/burooq.com/cert.pem
cafile /etc/letsencrypt/live/burooq.com/chain.pem
keyfile /etc/letsencrypt/live/burooq.com/privkey.pem

listener 8083

certfile /etc/letsencrypt/live/burooq.com/cert.pem
cafile /etc/letsencrypt/live/burooq.com/chain.pem
keyfile /etc/letsencrypt/live/burooq.com/privkey.pem

寻找所有打开的端口，我得到：

解决方案

您不能使用 IP 地址，您必须使用您获得证书的主机名，例如 burooq.com

原因是浏览器将无法验证来自代理的证书，因为它没有 IP 地址的 CN 或 SAN 条目。

您还需要确保防火墙配置为允许端口 8083 上的外部访问

编辑：

同样刚刚仔细检查了 HiveMQ Websocket 展示页面，它看起来不支持通过 Websockets 代理连接到 TLS 安全的 MQTT。
