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!
Here it is starting up:
