ESP32 Webserver on ESP-IDF - E (14713) httpd: httpd_server_init: error in listen (112), still webpage is getting loaded

[shruti_patel]

Hi, I have implemented BLE+ Webserver ESP32 Wroom 32D board. Initially I was facing issue with loading webpage after connecting to Access Point on ESP32, but now, I am able to load the webpage page but on serial terminal it is showing me an error "E (14713) httpd: httpd_server_init: error in listen (112)" "I (14723) webserver: Error starting server!".

Sometimes the page is not getting fully loaded, It get stuck while updating data on webpage, although images are getting loaded.

I have not used any external library in the code, below is the list of files I have included:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_system.h"
#include "esp_spi_flash.h"
#include "esp_http_server.h"
#include "esp_spiffs.h"
#include "esp_wifi.h"
#include "esp_event.h"
#include "freertos/event_groups.h"
#include "esp_log.h"
#include "nvs_flash.h"
#include "esp_netif.h"
#include "driver/gpio.h"
#include <lwip/sockets.h>
#include <lwip/sys.h>
#include <lwip/api.h>
#include <lwip/netdb.h>
#include <lwip/err.h>
#include <sys/param.h>
#include "file_variables.h"
#include "cJSON.h"

Please guide me regarding the error, as it is randomly generated, I don't see it every time while accessing webpage.

Thanks you!

It seems the two listen TCP pcb exists and there local ip and port is the same. The address and port are already used.
