chengr28 added a comment to T7577: GnuPG could not work when TCP congestion provider is set to BBR2 in Windows.

Spent some time discovering and unfortunately it's Windows's bug in loopback interface.
I wrote a test demo (blocking mode) to exchange data and watched their packets, found that network stack would drop packets when congestion control algorithm is set to BBR2. It seems the second data exchange was broken.

And thanks gniibe! I have tested 2.4.1 several times in this month (including existing and new keys), the warning was never shown again.

Hi zhangguangzhi, I think that it's version-specific problem.
I traced the chain and this warning message was added in release 2.3.3 T5565.
The problem should be able to reproduce between 2.3.3 and 2.4.0.
