Hardware:

Board: FireBeetle-ESP32 (ARDUINO IDE BOARD SELECTION)
Core Installation version: V1.0.4
IDE name: ARDUINO IDE V1.8.13
Flash Frequency: 80Mhz
PSRAM enabled: NOT SPECIFIED IN ARDUINO IDE

Description:

Describe your problem here
We are trying make WEBSERVER using ESP32, on which we are accessing our designed webpages.
these webpages are written in HTML and CSS.

  • AP MODE used for the ESP32 WEBSERVER.
  • Webpages are not accessible in a web browser after successful connection with Access point of ESP32.

Sketch: (leave the backquotes for code formatting)

//Change the code below by your sketch
#include <WiFiClient.h>
#include <ESP32WebServer.h>
#include <WiFi.h>
#include <ESPmDNS.h>
#include "webpage.h"

String defaultAP = "apmode";
String defaultPASS = "11111111";

ESP32WebServer server(80);



void handleRoot() {
//  server.send(200, "text/plain", "hello from ESP32!");
server.send(200, "text/html", userlogin());
}

void handleNotFound(){
  String message = "File Not Found\n\n";
  message += "URI: ";
  message += server.uri();
  message += "\nMethod: ";
  message += (server.method() == HTTP_GET)?"GET":"POST";
  message += "\nArguments: ";
  message += server.args();
  message += "\n";
  for (uint8_t i=0; i<server.args(); i++){
    message += " " + server.argName(i) + ": " + server.arg(i) + "\n";
  }
  server.send(404, "text/plain", message);
}

void setup(void){
  Serial.begin(9600);
  Serial.println(" ");
  Serial.println("Configuring access point...");
  Deafault_AP_MODE();

  delay(100);


  server.on("/", handleRoot);

  server.on("/inline", [](){
    server.send(200, "text/plain", "this works as well");
  });

  server.onNotFound(handleNotFound);

  server.begin();
  Serial.println("HTTP server started");

Use board "ESP32 Dev Module". Set Core Debug Level to verbose. This will give you more logging information.
protip: If you want help with your code, it should directly compile.

I think this is a duplicate of #2025, which has not been fixed.

Edit: Does not seem to be a duplicate. I mistakingly ignored the fact that your device doesn't crash.

So, your issue is only with your Windows 10 PC connecting to the device? Your android phone is able to browse the web page? Disconnect your pc from any other networks (even wired), and try again.

From your screenshot your are still connected to a wired network. The most os‘s route traffic to the network port that is online even if you use a ip as adress.
F.e. on ios i got problems getting the website of the esp because the iphone tries to connect to 192.168.4.1 over the mobile data. Try to give your pc only the esp wifi and no other network connection
