4 years ago @kelunik This is still an issue on Windows/PHP 7.4. Happens frequently with Xdebug enabled (about 50% of the time).
In BasicResolver.php line 149:

A little over 50% of the time, a async CLI application fails to start on Windows because the DNS doesn't work. Once it works, the problem does not seem to occur again, but there's a high probability it will fail unrecoverably at each process start. The operation is retried 5 times and the same error continues to occur until a new PHP process is started, when the dice is re-rolled to see if DNS is actually going to work. It doesn't matter if a process successfully ran a few seconds ago, all rolls are independent and have an equal chance of failing, despite recent successful resolutions by another process.
