snapdragon 636
strace http://prntscr.com/ouujos

it runs perfectly by windows. but on my linux(Termux) arm64 snapdragon 636 its blocking when i call SSL_connect.

Is this still an issue?

What version of OpenSSL are you using?

All is ok. Sorry :c

SOCKET connection = socket(
pAddrInfo->ai_family, //AF_INET
pAddrInfo->ai_socktype, //SOCK_STREAM
pAddrInfo->ai_protocol //IPPROTO_TCP
);

I have to replace these parameters with constants.
