Poco c++ x64 stops after SecureSMTPClientSession.open() - c++

Question

I learn how to use C++ for network stuff, so first thing i tried is to send email with Poco C++ library. I used vcpkg to install poco with openssl, and it compiles fine
I take code like example from that question:
Sending HTML code in a mail using Poco library
Where dude could send text, but couldn't send file, so i thought that i could reproduce his result quickly, and send some text too, but it doesn't works at all
It Creates Secure SMTP session, but when i try to open it, program just stops
There's my code:
#include <Poco\Net\AcceptCertificateHandler.h>
#include <Poco\Net\FilePartSource.h>
#include <Poco\Net\InvalidCertificateHandler.h>
#include <Poco\Net\MailMessage.h>
#include <Poco\Net\NetException.h>
#include <Poco\Net\SecureSMTPClientSession.h>
#include <Poco\Net\SSLManager.h>
#include <iostream>
namespace pn = Poco::Net;
struct info
{
std::string sender;
std::string recipient;
std::string password;
std::string host;
int port;
};
void MailSender(info a)
{
Poco::Net::MailMessage mailMessage;
mailMessage.addRecipient(Poco::Net::MailRecipient(Poco::Net::MailRecipient::PRIMARY_RECIPIENT, a.recipient, "username"));
mailMessage.setSubject("test");
mailMessage.setSender(a.sender);
mailMessage.setContent("Oh yeah!\r\n");
Poco::Net::SecureSMTPClientSession session(a.host, a.port);
std::cout << "> Session created\n";
session.open();
std::cout << "> Session opened\n";
Poco::Net::initializeSSL();
std::cout << "> SSL initialized\n";
Poco::SharedPtr<Poco::Net::InvalidCertificateHandler> ptrHandler = new Poco::Net::AcceptCertificateHandler(false);
Poco::Net::Context::Ptr ptrContext = new Poco::Net::Context(Poco::Net::Context::CLIENT_USE, "", Poco::Net::Context::VERIFY_RELAXED, 9, "ALL:!ADH:!LOW:!EXP:!MD5:#STRENGTH");
Poco::Net::SSLManager::instance().initializeClient(NULL, ptrHandler, ptrContext);
std::cout << "> Client initialized\n";
try
{
session.login();
std::cout << "> 1 login completed\n";
if (session.startTLS(ptrContext))
{
session.login(Poco::Net::SecureSMTPClientSession::AUTH_LOGIN, a.sender, a.password);
std::cout << "> 2 login\n";
session.sendMessage(mailMessage);
std::cout << "> Message sent\n";
}
session.close();
std::cout << "> Session closed\n";
Poco::Net::uninitializeSSL();
}
catch (Poco::Net::SMTPException& e)
{
std::cout << e.message() << std::endl;
session.close();
Poco::Net::uninitializeSSL();
}
};
int main()
{
info a{ "username#yandex.ru" , "username#yandex.ru" , "application_password" , "smtp.yandex.ru" , 465};
/*
*a.sender = "username#yandex.ru";
*a.recipient = "username#yandex.ru";
*a.password = "application_password";
*a.host = "smtp.yandex.ru";
*a.port = 465;
*/
MailSender(a);
}
Yandex provides instruction for their smtp usage:
https://yandex.ru/support/mail/mail-clients/others.html
Mail server address - smtp.yandex.ru
Port - 465
Security - ssl
I tried mail.ru and yandex.ru with the same result - nothing
I tried version without ssl, still nothing
I tried to turn off my antivirus
