为什么要使用ODBC连接SQL Server?

// 因为修改了好几次，所以信息我已经对不上了，大概出现了下面的这些
Connection Timeout Expired. The timeout period elapsed during the post-login phase. The connection could have timed out while waiting for server to complete the login process and respond; Or it could have timed out while attempting to create multiple active connections. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=3; handshake=10; [Login] initialization=0; authentication=0; [Post-Login] complete=14074;

或者

Microsoft.Data.SqlClient.SqlException (0x80131904): A connection was successfully established with the server, but then an error occurred during the pre-login handshake.
(provider: SSL Provider, error: 31 - Encryption(ssl/tls) handshake failed)
System.IO.EndOfStreamException: End of stream reached

或者

SSL Handshake failed with OpenSSL error - SSL_ERROR_SSL。
