You are supposed to specify the Port number in the URL itself, ie:

Connect() does not have a Port parameter.

Get() (and Post()) extracts the port number from the specified URL,
defaulting to 80 if not present, and then (re-)connects accordingly.  Since
your web server is not running on port 80, TIdHTTP cannot connect to it.

As well it should.

There is such a property.  Get() and Post() assign it dynamically based on
the specified URL, because the HTTP protocol requires the port number to be
specified in the URL in the first place.
