Hi

I an trying to connect to a server using FTPS(TLS), but when I do that I get problem when the data connection are about to be setup. I think the problem are on the server side but I have to prove that to my customer

. Can anyone confirm this by looking at the log below, or have I missed something? Looks like firewall issue on the server side. Other possible reasons for this error?
