Network ports not availabe for OTA, albeit network connections exist in WiFi domain.

[rin67630]

System Windows 10
Arduino IDE 1.8.13

Sometimes, for various reasons, the WiFi network connection is delayed upon rebooting Windows.
Windows shows first a disconnected world symbol and connects automatically later (delayed by approximately 30 seconds) to the WiFi.

When that happens, the Arduino IDE 1.8.13 will not show up any available OTA ports, and only displays serial ports.

This effect occurs irrespective of which time you start the Arduino IDE 1.8.13, even if you start it much later to a time where the WiFi connection is absolutely available.

Restarting the Arduino IDE does not help, restarting the computer does not help neither.
There is something like a flag set "no network was available on booting" and then the IDE would not provide the network ports.

This is extremely annoying, since you cannot use OTA, even if you have the right network live upon starting the Arduino IDE.

Could be possible to get information on how to prevent this behaviour?
What is actually the Arduino IDE sensing to provide or not provide network ports?
Could it be changed to a situative test at the time of starting the IDE?

Thank you for your help!

In fact I was victim of this infamous Windows behavior:

(not the problem, the flaw came again after fixing that)

Halas, I got the missing network ports problem again.
I just cannot figure out how to track the problem.
When this happens, the WiFi network supporting the OTA clients (many) ist available and the computer is connected to them. The only problem is that the Arduino IDE does not recognize the ports.
Restarting the IDE does not help.
Rebooting the computer helps sometimes, mainly not.
A complete shutdown, and full restart usually helps... for some time.
Then, hours later, the network ports are there again just to disappear again later...

Could you, please, please, give me some indications on how to track down this problem?
Some logs?
Some procedure to force the IDE to rescan the network ports?
Some indication on how and when the OTA ports are gathered.

Thank you for any assistance, i get crazy with this behavior!

When the ports ar missing I get this info on the bottom of my IDE:

How can one dig further to know WHICH error on 192.168.188.76 the IDE is complaining of?

Off course the target is present and has an OTA code:
