Error: Transferred a partial file

Aleksander Lanes 5 years ago in iPad updated by Alexander Blach (Developer) 5 years ago 4
I am getting an error when uploading files when using FTPS.

Errors occured
Error uploading "myfilename": Transferred a partial file

On the server the file is replaced with an empty file (if I enable "keep partial uploads" on the server)

I am running the 5.1.1 version on an iPad with iOS 8.1.1. I had exactly the same issue when running iOS7.

Please try to enable the "Debug Log" setting in the connection's settings screen. Tap on the (i) button on the right side of a connection to change its settings. This creates a log file when you try to connect to the server which might help you find out what's wrong.
I had a look at the log file, but I am not that much wiser. There are a few warnings about the certificate being issued for a different domain to where I am connecting (I am connecting via local IP), but I do not see how that can be related.

The actual errors related to the file seems to be the following:
"0000: 550 The system cannot find the file specified. .== info: Given file does not exists."

I can upload files via normal FTP using Textastic, and I can upload files via FTPS using Filezilla from a different computer. I am however seeing some strange behaviour in Filezilla where the file is uploaded and then I get a warning about overwriting the file I just uploaded.

Seems this may be a server issue, and not a Textastic bug. I need to investigate a bit more, but I may have reported a false positive here. Sorry if so :/

It appears this was an issue with TLS 1.2 on Windows FTP servers. Hotfix available here:

Not sure why Textastic gave a different error message than Filezilla, but the error in Filezilla (550: The supplied message is incomplete. The signature was not verified.) pointed me directly to the microsoft hotfix.

It's great to hear that you could figure out the problem.
