transfer of files with 0KB

[pakual]

Hi friendly reader.
I am currently testing flashfxp and the program runs well despite one major problem: when I try to transfer files from one ftp (both bullet proof ftps) to another- the file contains nothing (0kb). I tried the change the preferences abit ( passive mode etc) no success. Is there anything I could change to solve this problem? thanks for any hint! cheers!

what version and build of flashfxp?

it's impossible to troubleshoot your problem with a single error line.
post full session.

since you totally mangeled ip information in those commands, it's impossible to say if the reported ips are accurate.
however the following looks wrong

[L] 227 Entering Passive Mode (XXX,XXX,XX,XXX,44,XXX)
[R] PORT XXX,XXX,XXX,XXX,XX,XXX
[L] 421 Unable to accept data connection. Service unavailable.
[R] 200 Port command successful.

your [R] server tried to connect to [L], [L] reported back that it refuses to accept that connection but [R] said it connected fine.

if FXP enabled on both of your servers? do you have proper ports allowed in your server's firewall?
