Thanks for this great site!
Just found and tested your ftp downloader code. It worked nice for two days. Then it stopped functioning. Though i have changed network, i wonder if there is anything to do with that. I can access the ftp located file via Total commander of via a direct ftp connection setup in explorer, however filezilla fails for some reason. I wonder too if it is a server site problem. Where shall i look for log?
I would bet that it is a problem of a proxy server being used in your new network. You can add a line using InternetSetOption function. See documentation here:
You should be able to find the proxy details in your Internet Explorer (Edge) browser settings.
