wemos d1 mini is not discovered

[djoe78]

Hi, for a year i have been using many wemos d1 mini without problems with this library for home automation lights and i have never had problems. For a few weeks, however, I have been having trouble controlling wemos via the echo dot gen.3 or from the app (device is not responding). I have eliminated the devices I can no longer find them, unless I restart the router but still have control problems. Before these problems when I was going to the ip of a wemos it showed me correct the devices I had defined. Now show me the following message: "Not Found (espalexa-internal)". I use the esp8266 core version 2.4.2 and i not use the async server mode. I try a new wemos d1 mini with last update of this library and async server mode, but I still can't discover it, so i enable debug mode:

the old devices compiled in January still work.
