Igor Sapego commented on IGNITE-8394:
-------------------------------------
The issue was that when using asynchronous connection it is preferred to use
{{SSL_connect}} instead of \{{BIO_do_connect}}. Also, it is needed to check
return of the {{SSL_get_error_}} after connect for {{SSL_ERROR_WANT_WRITE}},
{{SSL_ERROR_WANT_READ}} and {{SSL_ERROR_WANT_CONNECT}} values, as they are not
errors, but instructions on the next connection step. Weirdly enough,
reproduced only on the remote host (maybe because of the longer network delay).
> ODBC: Can not establish SSL connection to remote host.
