长链接配置：客服后台老是断开

环境win server 2019，宝塔7.9，nginx,PHP7.4和7.3都试了，mysql5.7，版本5.2.2

配置了nginx反向代理，

location /notice {
    proxy_pass http://127.0.0.1:50001/;  
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-real-ip $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
}
location /msg {
    proxy_pass http://127.0.0.1:50002/;  
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-real-ip $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
}

宝塔和服务器端口50001-50013都开了。

powershell运行了

php think queue:listen --queue

php think timer start --d

直接运行了crmeb目录下的workerman.bat，客服后台能发消息，但是过几分钟就不行了，客服发不出，客户那显示客服连接中，然后是连接失败
