My questions are:

This is kinda strange that Chilkat is trying to use connection via http with port 80, especially when the URL string contains "https://"

Why this function is trying to use port 80?

How to force Chilkat to use SSL on port 443?

Remark: I checked the URL which I provide with Google Chrome and this browser was able to download this particular file on exactly the same computer.

Answer 1

Look closely at the URL within the Chilkat LastErrorText. Your application passed "https:\\*****.exe". Notice that you used backslashes instead of forward slashes after "https:". The backslashes caused the URL parsing to return garbage results..
