使用GB28181协议在订阅后流被断开该如何解决

使用设备为海康摄像头，配置如下：

config.yaml配置如下

llhls:
  enable: false
hls:
  enable: false
monitor:
  enable: false

global:
  pulseinterval: 5s # 心跳事件间隔时间

gb28181:
  invitemode:     1 #0、手动invite 1、表示自动发起invite，当Server（SIP）接收到设备信息时，立即向设备发送invite命令获取流,2、按需拉流，既等待订阅者触发
  position:
    autosubposition: false #是否自动订阅定位
    expires: 3600s #订阅周期(单位：秒)，默认3600
    interval: 61s #订阅间隔（单位：秒），默认6
  sipip:          "" #sip服务器地址 默认 自动适配设备网段
  serial:         "34020000001110000001"
  realm:          "3402000000"
  username:       "34020000001110000001"
  password:       "12345678"
  registervalidity:  80s #注册有效期
  mediaip:          "" #媒体服务器地址 默认 自动适配设备网段
  port:
    sip: udp:5060 #sip服务器端口
    media: tcp:58200-59200 #媒体服务器端口，用于接收设备的流

  removebaninterval: 10m #定时移除注册失败的设备黑名单，单位秒，默认10分钟（600秒）
  loglevel:         debug

启用monibuca进程，查看8080/gb28181/api/list API接口返回如下：

观察到的现象：当播放失败后，8080/gb28181/api/list这个API的返回对象就会变为[]空数组目前看起来连接是建立了，从报错内容来看是没有收到推流数据，想请教一下该如何排查问题。服务器上的端口已经全部开放（1-60999）
