Ensure your loader version matches the 22.3 software exactly. Using a 21.x loader with 22.3 software is the fastest way to cause a connection failure. Test the Port: Once launched, go to Options > Test

Based on your request, I have interpreted "vcds 223 loader better download" as a prompt to design a software feature that improves the download and installation experience for a tool of this nature (often referred to as a "Loader" or "Manager").
