Issue with a connection MQTT over TLS with Ethernet W5500

[MaxiLargo]

Description

Steps to Reproduce

boolean reconnect() {
  chipId = ESP.getEfuseMac();
  char chipIdString[18];  
  snprintf(chipIdString, sizeof(chipIdString), "%04X%08X", (uint16_t)(chipId >> 32), (uint32_t)chipId);

  if (client.connect(chipIdString, mqtt_username, mqtt_password)) {
    client.publish("test", message.c_str());
    conectado.store(true);
  }
  return client.connected();
}

void mqttTask(void* param) {
  while (1) {

unsigned long cu = millis();

if (cu - lastReconnectAttempt >= 60000) {

    String message = "....";

    if (!client.connected()) {
        reconnect();
      }else {
        client.loop();
    }

  }

  unsigned int highWaterMark = uxTaskGetStackHighWaterMark(NULL);
  Serial.print(highWaterMark);

  lastReconnectAttempt = cu;
}
  vTaskDelay(pdMS_TO_TICKS(60000));
}
}

static const char* root_ca PROGMEM = R"EOF(
...
)EOF";

EthernetClient ethclient;
SSLClient seceth(&ethclient);
PubSubClient client(seceth);

void setup() {
  WiFi.mode(WIFI_STA); 
  Serial.begin(115200);
  disableCore0WDT();
  disableCore1WDT();
  M5.begin();        
  M5.Power.begin();

  uint64_t chipId1 = 0;
  chipId1 = ESP.getEfuseMac();

  char chipIdString[18];
  snprintf(chipIdString, sizeof(chipIdString), "%04X%08X", (uint16_t)(chipId1 >> 32), (uint32_t)chipId1);
  Serial.print(chipIdString);
  String ssid = "indulink" + String(chipIdString);

  if (!SD.begin()) {
        M5.Lcd.println("Card failed, or not present");
        while (1);
    }
    M5.Lcd.println("TF card initialized.");

    while (!module.begin(&Wire, 21, 22, MODULE_4IN8OUT_ADDR)) {
        Serial.println("4IN8OUT INIT ERROR");
        M5.Lcd.println("4IN8OUT INIT ERROR");
    }

    Serial.println("4IN8OUT INIT SUCCESS");

    M5.Lcd.println("Contador de pulsos iniciado.");

  SPI.begin(SCK, MISO, MOSI, -1);
  Ethernet.init(CS);
    while (!Serial) { }

  Ethernet.begin(mac);
  Serial.print("Ethernet iniciado. Dirección IP: ");
  Serial.println(Ethernet.localIP());
  timeClient.begin();
  timeClient.update();
  seceth.setCACert(root_ca);

  client.setServer(mqtt_server, mqtt_port);
  client.setCallback(callback);
  Reinicio.attach(2,reinicio);

  xTaskCreatePinnedToCore(
    mqttTask,    
    "mqttTask",  
    8192,         
    NULL,
    1, 
    NULL,
    0   
  );
  xTaskCreatePinnedToCore(
    countTask,   
    "countTask", 
    8192,       
    NULL,
    1,  
    NULL,
    1   
  );
}

Expected Behavior

Publish a variable in a broker mqtt over tls with ethernet

Actual Behavior

when the mqtt task run, this error appears

[ 62514][E][ssl__client.cpp:42] _handle_error(): [start_ssl_client():367]: (-1) ERROR - Generic error [ 62515][E][SSLClient.cpp:242] connect(): start_ssl_client failed: 0

Environment

• Operating System: [Windows 10 Home]
• Version: [22H2]

IDE

• [x] Arduino IDE
• [ ] PlatformIO IDE extension

Additional Context

It is a very big program, try to show the functions that are used by the mqtt task

Hi @MaxiLargo Have you got anywhere with this?

1. Be good to see the output when log level set to debug.
2. Have you set the flag for the W5500 #define W5500_WORKAROUND . It is recommended.

Ensure you are the latest version of this lib 1.3.1.

Hi @RobertByrnes! I try to set the debug level (seceth.setDebugStream(&Serial)) but it doesn't work. And yes, I have the flag #define W5500_WORKAROUND and also I tried with #define _W5500_H_ but it is the same result, i have the last version of the lib.

If you can help me I would appreciate it

ok @MaxiLargo can you share a longer excerpt from log file that shows the entire connection process leading up o these 2 errors:

[ 62514][E][ssl__client.cpp:42] _handle_error(): [start_ssl_client():367]: (-1) ERROR - Generic error
[ 62515][E][SSLClient.cpp:242] connect(): start_ssl_client failed: 0

Here it's the log:
