That is normal behavior for TCP. Your connection was abnormally lost. When
the connection is reestablished, the remote machine reports back to your
machine that the socket stack on the remote machine has been reset. The
only thing you can do is wrap the Connect() is a try..except block and try
again.

A try..finally block does not catch exceptions. It only executes the code
inside the 'finally' section and then allows the exception to continue along
the call stack. To actually catch the exception, you need to use a
try..except block instead.

There isn't any. You have to fully disconnect and then reconnect fresh.

You should never be calling Close() directly at all. To disconnect
properly, you should be calling TIdFTP's Quit() or Disconnect() method
instead.

Exactly. Which is why you should not be trying to access the Socket
property like you are.

Use the Disconnect() method instead.
