TelnetStream doesn't stop on ESP32

[Layochi]

Hello everyone!
I have a problem with this library... When using
TelnetStream.flush();
TelnetStream.stop();
ESP32 does not close the communication.

I attach my code here so you can help me. The idea of this code is to close the communication when 'C' is written in the terminal. It works because the message "Closing the Telnet Communication..." is displayed but the communication remains effective.

Thanks in advance for your help !

#include <TelnetStream.h>

void setupOTA() {
  Serial.println("Starting Telnet Communication...");
  TelnetStream.begin();
  Serial.println("Telnet Initialized!");

  Serial.println("You can open a new terminal and write the command:\n$ telnet " + WiFi.localIP().toString());
}

void debug(const char* string) {
  Serial.print(string);
  TelnetStream.print(String(string));
}

void debugln(const char* string) {
  Serial.println(string);
  TelnetStream.println(String(string));
}

void handle() {
  switch (TelnetStream.read()) {
    case 'C':
      TelnetStream.println("\nClosing the Telnet Communication...");
      TelnetStream.flush();
      TelnetStream.stop();
      break;
    case 'R':
      debugln("\nRebooting...");
      ESP.restart();
      break;
  }
}
