Question

我正在使用以下代码，以便通过手机热点控制ESP8266。

/*

#include <ESP8266WiFi.h>
#include <WiFiClient.h>

//ESP Web Server Library to host a web page
#include <ESP8266WebServer.h>

//---------------------------------------------------------------
//Our HTML webpage contents in program memory
const char MAIN_page[] PROGMEM = R"=====(

//On board LED Connected to GPIO2
int LED=5;  

//SSID and Password of your WiFi router
const char* ssid = "Jms";
const char* password = "ab12";

//Declare a global object variable from the ESP8266WebServer class.
ESP8266WebServer server(80); //Server on port 80

//===============================================================
// This routine is executed when you open its IP in browser
//===============================================================
void handleRoot() {
 Serial.println("You called root page");
 String s = MAIN_page; //Read HTML contents
 server.send(200, "text/html", s); //Send web page
}

void handleLEDon() {
 Serial.println("LED on page");
 digitalWrite(LED,HIGH); //LED is connected in reverse
 server.send(200, "text/html", "ON"); //Send ADC value only to client ajax request
}

void handleLEDoff() { 
 Serial.println("LED off page");
 digitalWrite(LED,LOW); //LED off
 server.send(200, "text/html", "OFF"); //Send ADC value only to client ajax request
}
//==============================================================
//                  SETUP
//==============================================================
void setup(void){
  Serial.begin(115200);
  WiFi.begin(ssid, password);     //Connect to your WiFi router
  Serial.println("");

  //Onboard LED port Direction output
  pinMode(LED,OUTPUT); 
  //Power on LED state off
  digitalWrite(LED,LOW);

  // Wait for connection
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  //If connection successful show IP address in serial monitor
  Serial.println("");
  Serial.print("Connected to ");
  Serial.println(ssid);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());  //IP address assigned to your ESP

  server.on("/", handleRoot);        //Which routine to handle at root location. This is display page
  server.on("/ledOn", handleLEDon);  //as Per  <a href="ledOn">, Subroutine to be called
  server.on("/ledOff", handleLEDoff);

  server.begin();                  //Start server
  Serial.println("HTTP server started");
}
//==============================================================
//                     LOOP
//==============================================================
void loop(void){
  server.handleClient();          //Handle client requests
}

通过使用我的共享热点连接到Internet的设备在html页面中使用ESP8266 IP地址，一切都可以正常工作。但是我无法使用来自其他Internet访问点的Internet访问该html页面。是什么原因，我该如何解决？
