I know I should probably put this in the ftp settings thread, but I wanted to use the public forum in case someone had good advice or suggestions...
For the past few years, those of us who use the DC server probably rely on our trusty Filezilla settings to get in. What I don't understand is why just about all the other ftp clients don't seem to work. I really would like to get the logins to work with DOpus (which I paid extra to get the secure ftp features) and cuteftp, which is supposed to be an enterprise level ftp client. Now, ever since the explicit-tls move a few years back, just about all these clients and probably others have a difficult to impossible time connecting to the DC server. Can we try to fix this or nail what the issue actually is? We've privately gone around and around on this before, but no answer seems to come up. I also don't want to bother mouser and gothic with it until we figure out where the issue is arising, as they are already very busy.
So the question is: what is filezilla doing that the other clients can't do? And if it is clicking a setting or two, which of the settings is it? I'll personally be specifically interested in DOpus and Cuteftp.
 just fyi, I used to use the server a lot and stopped the last 3 years preciesly because of this issue. I went from transferring files back and forth easily to spending most of my time trying to figure out why it doesn't work, and I essentially gave up. Also, it stopped working at work. So what happened is that I could only try to use it for a couple of hours in the evening when I was NOT at work and had all my clients and settings to play around with freely. As a result, I stopped updating my dc website.
