Sketch

WiFi.mode(WIFI_STA);

        wm.addParameter(&paramMqttServer);
        wm.addParameter(&paramMqttPort);
        wm.addParameter(&paramMqttUser);
        wm.addParameter(&paramMqttPassword);

        std::vector<const char *> wm_menu = {"wifi", "exit"};
        wm.setShowInfoUpdate(false);
        wm.setShowInfoErase(false);
        wm.setMenu(wm_menu);

        bool res = wm.autoConnect(_SSID);

Hmm how tf is _connectretries increasing? Lol what in the world

[rusty-labs]

There is only one reason

if (info.wifi_sta_disconnected.reason == WIFI_REASON_ASSOC_FAIL)
    {
      if (_aggresiveReconn)
        _connectRetries += 4;
      DEBUG_WM(DEBUG_VERBOSE, F("[EVENT] WIFI_REASON: AUTH FAIL"));
    }

_connectretries is increased exactly by 12, meaning that the code above is being called 3 times

What line is that code? I missed it

I am so dumb. Lol usually this error only happens once I guess this should only be set one time

[rusty-labs]

There is a typo if(_aggresiveReconn & _connectRetries<4)
