esp8266 mDNS 正在工作，但现在已停止
esp8266 mDNS was working, but has now stopped
我让 mDNS 响应器在我的 ESP8266 上工作。它已经工作了几个星期，我可以 ping、nslookup 并转到网页。我正在使用 win10 和 Android phone，两者都运行良好。
然后它似乎停止响应本地名称（IP 仍然可以正常工作）。
奇怪的是，当我打开控制台上的调试消息时，mDNS 似乎仍在工作，但客户端仍然找不到它。
下面是调试日志，但据我所知它应该可以正常工作。那里的任何 mDNS 专家都可以看到出了什么问题？
谢谢！
这里正在启动：

两天后拿起它，它开始工作...没有任何变化（至少在代码中）。
我让 mDNS 响应器在我的 ESP8266 上工作。它已经工作了几个星期，我可以 ping、nslookup 并转到网页。我正在使用 win10 和 Android phone，两者都运行良好。 然后它似乎停止响应本地名称（IP 仍然可以正常工作）。 奇怪的是，当我打开控制台上的调试消息时，mDNS 似乎仍在工作，但客户端仍然找不到它。
下面是调试日志，但据我所知它应该可以正常工作。那里的任何 mDNS 专家都可以看到出了什么问题？ 谢谢！
