Hi there.

I'm attempting to transmit a file, on a daily basis, from a Windows Server in my company to an external host using FTP over Explicit SSL.

I have already done a successful transmission using filezilla with the settings advised to me by the external host and the filewall team in my company. Here is the connection window...

And the log when I connect...

Unfortunately filezilla does not offer any scheduling or command line tool, so I am using cURL command line so that I can schedule the command in a windows batch and run it daily.

Here is the command I'm using on a windows cmd session...

Ø curl -T test.txt -user MMOFTP:Pass123 -url staging.missionmode.com:4121 -proxy proxy-ese.fr.world.delta:1080

where test.txt is a file in the same folder as the curl.exe
MMOFTP:Pass123 is my FTP username and password on the remote host
staging.missionmode.com is the address of the remote host
4121 is the port I'm told to connect on the remote host
proxy-ese.fr.world.delta is the proxy in my company's domain used for outbound connections over the internet
1080 is the port used by the proxy to get out of my company's firewall

and here is the response I get...

[cid:image002.png_at_01CC4310.2A6854C0]

If I change any of these details I get a connection error, so I think I am making a successful connection to the host but not getting any further. i.e. My test.txt file is not being transmitted.
Does anyone have any idea what "(52) Empty reply from server" means?

Many thanks
