Open Transport Error number 3155

I have a applescript that uploads PDF files to a ftp server. Occasionally I will recieve a “Open Transport Error number - 3155” from the script and of course the script icon starts bouncing up and down. I am wondering if anyone knows what it means, what causes it and how would I fix it (aside from upgrading fetch). I am not sure if you need any of the following information but I figured I’d throw it in just in case.

Script Editor- 2.0 (v43.1)
AppleScript 1.9.3

Mac OS 10.3.9

Fetch 4.0.1

Thanks

Open Transport hasn’t been used, to my knowledge, since OS 9, which makes sense since you mention Fetch. Since that’s the case, this message properly belongs in the Applescript | Mac OS forum.

I found a list of Open Transport error numbers, but I doubt it will tell you much. I’d suggest trading in Fetch (good as it was) for a modern FTP client or curl (builtin to the OS).
