The error code is not compiled: 'class WiFiServer' does not have a member named 'accept'

[GGI1]

Arduino: 1.8.19 (Windows 10), Плата:"LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

C:\Users\USER\Documents\Arduino\libraries\arduinoWebSockets-master\src\WebSocketsServer.cpp: In member function 'void WebSocketsServer::handleNewClients()':

C:\Users\USER\Documents\Arduino\libraries\arduinoWebSockets-master\src\WebSocketsServer.cpp:658:86: error: 'class WiFiServer' has no member named 'accept'

WEBSOCKETS_NETWORK_CLASS * tcpClient = new WEBSOCKETS_NETWORK_CLASS(_server->accept());

exit status 1

Compilation error for the board LOLIN(WEMOS) D1 R2 & mini.

I do not know how to fix it. Please help me :-(

I replaced accept() with available():

        // WEBSOCKETS_NETWORK_CLASS * tcpClient = new WEBSOCKETS_NETWORK_CLASS(_server->accept());
        WEBSOCKETS_NETWORK_CLASS * tcpClient = new WEBSOCKETS_NETWORK_CLASS(_server->available());

Compilation is ok and initial work also. I can connect to the http://192.168.4.1 and put the WiFi SSID/Password.
But after restart the web server is always returning: "Not Found:"

Edit:
ok, firmware update page is available (login required):

going to try Serial communication.

I have this same problem. Since it was working before I think it is a problem with a new version. I will look further into it later. For now I was able to fix it pointing my dependency directly to the version 2.4.0
Using PlatformIO you need to change you platformio.ini file like this:

...
lib_deps=
    https://github.com/Links2004/arduinoWebSockets#2.4.0

In my case this was happened in vise versa:

The library has not trouble on ESP32, but gave an introduced warning on Raspberry Pico W. The Arduino IDE version is 2.3.2
