Cannot use socket.io and HttpClient at the same time

[xdien]

I'm having a problem with HttpClient when socketio is opening a connection. Httpclient always return fasle(conection failed) when Socketio is connecting. When I disable socketio.loop() or wait for socketion to disconnect due to timeout then I can use httpclient.

{
public:
    HttpsAPIHelper(String url);
    ~HttpsAPIHelper();
    bool makeEndInfo(String &json);

private:
    // Fingerprints sha-1
    const uint8_t fingerprint[20] = {hiden};
    String url;
    String token;

    https = new HTTPClient();
    url_log_activities = url + "/sensor-activity-logs";

#ifdef SSL
    client = new BearSSL::WiFiClientSecure();
    client->setFingerprint(fingerprint);

}

{
    delete https;
}

{
    // https.connected
    // https.useHTTP10(true);
    if (https->begin(*client, url_log_activities))
    {
        https->addHeader(F("Content-Type"), F("application/json"));
        https->addHeader(F("Accept"), F("application/json"));
        system_print_meminfo();
        Serial.print("Free heap_size ") ; Serial.println(system_get_free_heap_size());
        int httpCode = https->POST(json);

        // httpCode will be negative on error
        if (httpCode > 0)
        {
            // HTTP header has been send and Server response header has been handled
            Serial.printf("[HTTPS] POST... code: %d\n", httpCode);
            // file found at server
            if (httpCode == HTTP_CODE_OK || httpCode == HTTP_CODE_MOVED_PERMANENTLY)
            {
                // String payload = https->getString();
                // Serial.println(payload);
                return true;
            }
        }
        else
        {
            Serial.printf("[HTTPS] POST... failed, error: %s\n", https->errorToString(httpCode).c_str());
            Serial.println(url);
        }
        // https->clear();
        https->end();
    }
    else
    {
        Serial.printf("[HTTPS] Unable to connect\n");
    }
    return false;
}

In main loop() function like this

loop(){
  socketio.loop();
  if(milis() - timeout >50000)
  {
    String json = "{\"data1\":55}";
    api->makeEndInfo(json);
    timeout = milis();
  }
}

Has everyone been like this?

I encountered the same problem with beginSSL.

The interesting thing is that esp socketIO can connect to my HTTPS server without fingerprint or CA with the beginSSL() function.

My server does not accept any insecure connection and upgrades every requests to HTTPS. And the socket connection works regardless. But every HTTP requests ( with CA ) stopped working...

I found the problem. esp8266's memory is too low to run socketio and https in parallel. if you turn off either one it will work fine.

the axTLS can only handle one active TLS / SSL connection. https://github.com/Links2004/arduinoWebSockets/issues/756#issuecomment-1163121901
