Read data from EEPROM problem

Hello

timer0.attach(10,ReConfig);
while (WiFi.status() != WL_CONNECTED) 
{
    delay(500);
    Serial.print(".");
}

You never stop this timer0 so ReConfig will be called even when Wifi has connected

I suggest that you don't use this Ticker thing, instead increase a counter inside the while loop and call ReConfig when this counter reach a value like 20
