Receiving 550 error code when transferring certain files but not all files.

[Caitlyn Nicol Miller]

While transferring files from my files to the files of my server, certain files are failing to transfer.

Basic info,
This is a mod for our ARK server hosted by PingPerfect.
This mod is already installed, these files are attempting to overwrite the existing ones as well as downloading new files from the update.
The issue only appears on certain files.

Other admins/moderators have attempted to resolve this issue by doing the update themselves and it has worked without issue. They also use the FileZilla client, there were no failed transfers on the same mod with the exact same update.
I have done two other mod updates within the last three days without issue.

Currently this is giving me an error:

It is the same the entire way up, only 34 files successfully transferred and 501 files that failed.

There's something wrong with the server. According to the log the target directory exists and the server is then being asked to create the file in it.

You need to contact your server administrator or server hosting provider for assistance to figure out why the server cannot find the file it is supposed to create.
