**Describe the bug**

Hello, I am using a Lolinv3 for operation. Everything works fine I use it mainly with web interface, I disabled mqtt. but after 1 day or 2 generally at night the bug module and the blue led of the Lolin flashes but it does not want to reconnect to the wifi.

I have to press the reset button on the Lolin to reconnect.
