On Demand Configuration Portal do not work

[mylms]

ESP32-C3
tzapu/WiFiManager@^2.0.17

I would like to use auto connect and manually start the ConfigPortal if manual configuration (MQTT etc.) is required. BUT there is "Do not use BOTH" in "On Demand Configuration Portal".
How to allow the user to automatically connect to a known WiFi (after start the device, if setting not required), but at the same time manually launch the Configuration portal with a button, for example?

• If I use "autoConnect" in setup ESP32 connects to Wifi

• If at the same time I use somewhere in the code (button event) "startConfigPortal", wifi is created, but it is not possible to connect to it (even the address 192.168.4.1 does not work).

• If I use "startConfigPortal" instead of "autoConnect" in setup, ESP does not connect to wifi.

• If I use only "startConfigPortal" it is possible to connect to ConfigPortal, but after exit it's not connected to wifi

void loop() { // is configuration portal requested? if ( digitalRead(TRIGGER_PIN) == LOW ) { WiFiManager wifiManager; wifiManager.startConfigPortal("OnDemandAP"); Serial.println("connected...yeey :)"); //**<<< NO, IT DOESN'T** } }

Problem solved!
I use WebServer WebServer.begin(); after wifiMngr.autoConnect.
Just deteled WebServer.begin(); and everything works!
