CTX = SSL_CTX_new is called only once, and SSL_2 = SSL_new is called twice.

When set in c.c (wolfSSL_CTX_set_cipher_list(CTX, "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA")) still fails (test2.pcapng).

In Ubuntu, clone Wolfssl-5.0.0 and then make and make install. Finally, running c.c will find that the second socket connection failed.

On the forum, I found a question almost identical to mine:https://www.wolfssl.com/forums/topic1626-ftps-data-port-failure.html.
His solution seemed to be to switch servers.

Also a log and pcap is very useful in determining why a connection is failing. If you'd prefer to keep this information private, please feel free to open a support ticket by emailing support @ wolfssl.com

When the client sends client Hello, the server simply replies with an ACK. The current test found that this server and VSFTP will have this phenomenon, other servers (such as Filezilla) can be successful. We also tested MBED SSL, which was successfully connected. Do you have friends who have encountered similar problems?

The attachment is the simulated FTPS code under Linux, and the address of the server is test rebex. net:990（195.144.107.198:990）.

gcc c.c -o C -lwolfssl       ./C 195.144.107.198 990
