[openssl-users] Issue with DTLS for UDP

[Grace Priscilla Jero]

Thankyou for the responses.
We figured the issue. But now we are getting error -5 from "SSL_connect"
and the errno is set to 22 which means invalid argument.
Is there a easy way to debug or get logs for SSL_connect.

Below is the sequence for the dtls udp connect that we are trying.
ssl = SSL_new(ctx)
bio = BIO_new_dgram(sock_id,BIO_NOCLOSE)
SSL_set_bio(ssl, bio, bio);
VI_res = SSL_connect(ssl)



Thanks,
Grace
