Websocket Secure crashes when connection to webserver is opened

[pam-param-pam]

Im using esp8288 nodemcu 12E v3

code bellow:

ESP8266WebServer server(80);
WebsocketsClient wsClient;

//other un important stuff

void loop() {

    switch (state) {
        case STATE_CONNECTING_TO_RELAY: {

            unsigned long wsLoopStartTime = millis();
            wsElapsedTime = wsLoopStartTime - wsStartTime;

            if ((wsElapsedTime >= 5000)) { //once every 5 seconds

              bool connected = wsClient.connectSecure("host", 443, "path");
              if(connected) {
                Serial.println("Connecetd to relay server!");
                changeState(STATE_RELAY_RUNNING);
              } else {
                  Serial.println("Not Connected!")
              }
              wsClient.onMessage([&](WebsocketsMessage message) {
                Serial.print("Got Message: ");
                Serial.println(message.data());
              });
              wsStartTime = wsLoopStartTime;
            }

            break;
        }

        case STATE_RELAY_RUNNING: {
            unsigned long wscLoopStartTime = millis();
            wscElapsedTime = wscLoopStartTime - wscStartTime;

            if ((wscElapsedTime >= 1000)) { //once every1 second
              if(wsClient.available()) {
              wsClient.poll();
            }
              wscStartTime = wscLoopStartTime;
            }

            break;
        }
    }
    server.handleClient();
    delay(100);
}

When websocket is succesfully connected, and i try to connect to AP Point the esp8266 crashes with:

if u need any more information, please tell me.

edit:

i found an old issue: there, it says it may have crashes due to no heap memory, so i printed the memory in a loop. THis is the last print before crash: ======FREE HEAP======== 7568

[furdog]

look at EXCVADDR: 0x00000000 There's something accessing NULL pointer It may be malloc or realloc exit with failure and some other code uses returned value without checks, which is usually a NULL pointer. 7kb heap available is pretty little, especially considering possible fragmentation. Backtrace looks quite bad. Hard to say where's exact point of failure. But it definitely related with malloc/realloc.

It is likely not an issue with your code, but the memory consumption and underlying library bug.
