你去掉设置 upgrade header 的两行看看，看起来是这个 header 导致的报错

是那个upgrade的双引号符号问题，现在emqx不报错了。

但是ssl 卸载还是有问题
表现出来的是

[2022-05-05 11:31:52] [INFO] Connect client ssl-ws, MQTT/WSS connection: wss://mqttyj.xxx.com:443/mqtt
[2022-05-05 11:31:52] [INFO] ssl-ws connect close, MQTT.js onClose trigger

点击连接后直接关闭， nginx 没有访问日志。

服务器配置的证书为泛解析证书 *.xxx.com 不知道是不是证书问题？


upstream empx_ws {
        server 172.19.70.37:8083 max_fails=2 fail_timeout=30s;
#       server 172.19.70.38:8083 max_fails=2 fail_timeout=30s;
}

server
{
        listen 80;
        listen 443 ssl http2;
        server_name apiyj.xxx.com mqttyj.xxx.com;
        index index.php index.html index.htm default.php default.htm default.html;
        root /apps01/localhost;

        ssl_certificate  cert_xxx/server.cer;
        ssl_certificate_key cert_xxx/server.key;


        location /account/ {
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_pass http://172.19.70.33:12000/;
        }

        location /upload/ {
                alias   /www/accountServer/upload/;
        }

        location / {
                proxy_redirect off;
                proxy_pass http://empx_ws;

                proxy_set_header Host $host;
                proxy_set_header X-Real_IP $remote_addr;
                proxy_set_header X-Forwarded-For $remote_addr:$remote_port;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
        }

        access_log  /apps01/logs/access.log;
        error_log  /apps01/logs/error.log;

但是直接用浏览器的mqtt.js 却能连上
