Port is discovered only intermittently using mdns-discovery, but instantly with Arduino IDE 1.x

[bartgrefte]

Describe the problem

When using Arduino IDE 2.x, mDNS detection only works intermittently.

When I use Arduino IDE 1.8.* the problem does not occur; mDNS detection works immediately.

To reproduce

Flash the "BasicOTA" example sketch of the "ArduinoOTA" library with the appropriate Wi-Fi credentials, to an ESP-module, Pico W or similar device.

Start both Arduino IDE 2.x and 1.x and see the immediate detection in 1.x and spotty (at best) detection in 2.x.

Expected behavior

mdns-discovery reliably discovers the network protocol ports of Arduino boards.

mdns-discovery version

1.0.9

Operating system

Windows

Operating system version

10 LTSB 2016

Additional context

I'm currently using Arduino IDE 2.3.2.

I'm surprised there isn't more buzz about this, OTA updates works very poorly because of this.

Maybe there are not enough people using this functionality?

In fact, many tutorials still recommend using IDE 1.18.19 due to the lack of adequate support for operating with ESP8266 and OTA sketch.

It's a shame for the Arduino IDE 2 programmers to have focused on appearance and not been able to maintain the functionality of IDE version 1.

It practically killed many projects, and to continue using it, programmers were unable to migrate to the new IDE 2.
