How do I use "Why Can't I Connect?"
I will attempt a connection to an FTP Server. Enter the server name or IP address and port (the default port for an FTP Server is 21.) I expect a response from this connection so I will wait for the response and close the connection on success.
Release 1.12.0
In this release
1. Added SSL / TLS support for IMAP, POP3, SMTP, LDAP, Usenet, and Generic Client connections.
2. Added a trace showing the SSL / TLS certificate information after a connection.
3. Fixed a bug when connecting a Generic Client that expects a response.

The SSL / TLS certificate information trace shows the valid date range and subject information if the trace detail level is set to Medium. The trace additionally shows the issuer information if the trace detail level is set to High.
