Basic Infos

Hardware

WiFimanager Branch/Release: Master

Esp32:

Hardware: ESP32 WROOM

Core Version: 2.4.0, staging

Description

the saved ap works fine when i put the usb cable and open the serial monitor, if i don't open the serial monitor throws me an authentication failed, ive tried to power with an switching source ive think that the current wasnt enough, but it still not working.

the connectTimeOut was changed to 60, 20 and 10 secconds and nothing.
