Describe the bug / Опишите ошибку программы
The blocked websites work fine in the Firefox browser, but curl can't access them. Here is an example:
>curl -v https://rutracker.org
* Host rutracker.org:443 was resolved.
* IPv6: (none)
* IPv4: 104.21.32.39, 172.67.182.196
* Trying 104.21.32.39:443...
* Connected to rutracker.org (104.21.32.39) port 443
* ALPN: curl offers h2,http/1.1
* TLSv1.3 (OUT), TLS handshake, Client hello (1):
* CAfile: D:\curl\bin\curl-ca-bundle.crt
* CApath: none
* LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to rutracker.org:443
* Closing connection
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to rutracker.org:443
