長鏈接配置：客服后臺老是斷開

環境win server 2019，寶塔7.9，nginx,PHP7.4和7.3都試了，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;
}

寶塔和服務器端口50001-50013都開了。

powershell運行了

php think queue:listen --queue

php think timer start --d

直接運行了crmeb目錄下的workerman.bat，客服后臺能發消息，但是過幾分鐘就不行了，客服發不出，客戶那顯示客服連接中，然后是連接失敗
