Originally created by @chandan-skillfinity on GitHub (Aug 2, 2018).
Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/682

Hardware: NodeMCU 1.0(ESP-12e Module)
Core Version: 2.4.1
Arduino IDE: 1.8.5
Operating System: MacOS High Sierra 10.13.6

Following 3 issues observed, request help in solving

  1. After going to AP mode, WiFi Manager not opening the configuration page.
  2. Sometimes the program also crashing
  3. Once mobile connects to AP MODE then neither it shows the web page nor it times out (it is stuck inside the method for ever)

Sketch

#include <ESP8266WiFi.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>
WiFiManager wifiManager;

void setup()
{
Serial.begin(38400);

Serial.println("entered setup");


wifiManager.setTimeout(60);

if(!wifiManager.autoConnect("AutoConnectAP"))
{
  Serial.println("failed to connect and hit timeout");
  delay(3000);  
}
else
Serial.println("connected");

}

void loop()
{
Serial.println("entered loop");

if(WiFi.status()== WL_CONNECTED)
{
   Serial.println("In Loop Connected");
}
else
{
    if(!wifiManager.autoConnect("AutoConnectAP"))
    {
      Serial.println("failed to connect and hit timeout");
      delay(3000);
     }
     else
     Serial.println("In loop connected");
}

}

not sure, sounds like a memory problem or sdk problem, try development, issues against master are ignored
