I am trying to access a FTP secured site (SSL/TSL) and transfer a file in VB.Net using FTPRequest. When I try to complete the transfer I get an error back "The remote certificate is invalid according to the validation procedure".

However when I connect to the same FTP site with FileZilla UI, I can transfer files with no problem. Why can do transfers with FileZilla and not in VB.Net? Does FileZilla have its own Certificate?
