尝试将我的 ESP8266 连接到我的 WebServer 时遇到一些问题。我想连接到 Web 服务器，然后通过 REST-API 将信息发送到服务器。

不幸的是，我的程序在连接到服务器时崩溃。

这是我的代码：

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

#ifndef STASSID
#define STASSID "SSID" //SSID
#define STAPSK  NULL //Password
#endif

const char* ssid = STASSID;
const char* password = STAPSK;

const char* host = "IP-Adress"; //Load Balancer IP
const uint16_t httpsPort = 443; //Load Balancer Port

// Use web browser to view and copy SHA1 fingerprint of the certificate
const char fingerprint[] PROGMEM = "FI NG ER PR IN T0";

void setup() {
  Serial.begin(115200);
  
  Serial.println("[INFO]\t\tStarting GPS Service");
  Serial.printf("[INFO] LAN:\tConnecting to WiFi '%s'", ssid);
  
  WiFi.mode(WIFI_STA); //Setting WiFi Client Mode
  WiFi.begin(ssid, password); //Connecting to WiFi
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(250);  Serial.print("."); //Waiting for WiFi Connection
  }
  Serial.print("\n");
  
  Serial.printf("[INFO] LAN:\tSuccessfully Connected to WiFi '%s'\n", ssid);
  Serial.print("[INFO] LAN:\tLocal IP-Address '");
  Serial.print(WiFi.localIP());
  Serial.print("'\n");
  
  Serial.printf("[INFO] WAN:\tConnecting to %s:%d\n" ,host, httpsPort);
  
  WiFiClientSecure client; // Use WiFiClientSecure class to create TLS connection

  Serial.printf("[INFO] WAN:\tUsing fingerprint '%s'\n", fingerprint);
  
  client.setFingerprint(fingerprint); //Set Fingerprint for WiFiClientSecure

  if (client.connect(host, httpsPort)) { //Here my Programm is Crashing
    Serial.printf("[INFO] WAN:\tSuccessfully Connected to WAN-IP '%s'\n", host);  
  } else {
    Serial.println("[ERROR] WAN:\tConnection failed!");
    return;
  }
  Serial.println("[INFO] WAN:\tClosing connection");
}

void loop() {
}

此时程序崩溃if (client.connect(host, httpsPort)) {

这是输出：

[INFO] Starting GPS Service
[INFO] LAN: Connecting to WiFi 'SSID'.
[INFO] LAN: Successfully Connected to WiFi 'SSID'
[INFO] LAN: Local IP address '192.168.178.*'
[INFO] WAN: Connecting to Server-Adress
[INFO] WAN: Using fingerprint 'FI NG ER PR IN T0'

有人知道如何解决这个问题吗？在此先感谢，帕特里克

我能够解决这个问题，完全重新安装了 Arduino Portable IDE 对我有用。
