ESP8266 WebServer not responding (connection time out)

Question 1

My web server running on ESP8266, stop working after while. I cannot connect to it - browser shows connection time out error. No error, no crash... nothing.

Have you any idea how to fix it?

My code:

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <NTPClient.h>
#include <WiFiUdp.h>
#include <ESP8266mDNS.h>
#include <FS.h>
#include "console.h"
#include "tictactoe.h"

Question 2

what version of the esp8266 arduino package you use?

Question 3

hmm... I am not sure what version do you mean but in Arduino Board Manager I have installed ESP8266 of version 2.0.0 Please specify more where I can find that version if this is not what are you want.

Question 4

What mime type is text/plane? Are you trying to transfer an aircraft?

Question 5

use the latest version 2.4.2

Question 6

@Majenko oops :D thanks for warning! I wrote it wrong and copy it to whole code, but its works good xD

Question 7

Use the latest version of Arduino esp8266 core package (2.4.2 or higher).
