esp8266 mDNS 正在工作，但现在已停止
我的 ESP8266 上运行了 mDNS 响应器。它已经工作了几个星期，我可以 ping、nslookup 并访问网页。我用的是win10和安卓手机，都很好用。 然后它似乎停止响应本地名称（IP 仍然工作正常）。 奇怪的是，当我在控制台上打开调试消息时，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工作。有 mDNS 专家可以看看出了什么问题吗？ 谢谢！
这里它正在启动：

I got the mDNS responder working on my ESP8266. It's been working for weeks, I can ping, nslookup and go to the web page. I'm using win10 and Android phone, both worked great.
Then it appeared to stop responding to the local name (IP still works fine).
The weird part is, when I turned on the debug messages on the console, mDNS still appears to be working, but the clients still can't find it.
Below are debug logs, but from what I can tell it should be working. Any mDNS experts out there that can see what is going wrong?
Thanks!
