Getting error 60 of curl to cygwin setup

[J M]

Hi,

This is a very painfull and weird failed error of Windows antivirus. I
apologize for not having realized before.

For other people who may encounter this difficult problem,  the key to find
this error is (cut connections only for sites that use Letsencrypt
certificates), is the strace /usr/bin/curl https://curl.se/

Here, the following line is the key:

--- Process 3100 thread 3124 created
 1668   16622 [sig] curl (3100) SetThreadName: SetThreadDescription()
failed. 00000000 10000000

This indicate the drop connection. I'm talking to the antivirus people to
solve this bug, I don't want to indicate the brand of the antivirus.

Many thanks to Brian for you help.
