Uploaded files at 0 bytes

#1 Post by SteeleR » 2019-04-10 14:53

Hello, since yesterday filezilla started uploading the files at empty. What I found so far under Windows 10 64 bit:

- works with files less that 100 byes or of the sort
- tried on several hostings and it has the same problem everywhere
- other FTP programs work correctly
- tried another network connection and the problem persists
- downgraded from 3.41.2 to 3.41.1 and the problem persists
- tried disabling NOD32 and the problem persist
- windows defender is disabled
- tried active/passive mode and forced UTF-8 and the problem persists

when the file is uploaded it does not give any errors but a success:
Status: File transfer successful, transferred 13,655 bytes in 1 second

when the file is slightly bigger I get an error and still a 0 bytes file after several confirmation messages:
Response: 150 Accepted data connection
Error: Received TLS alert from the server: Bad record MAC (20)
Response: 226-Error during read from data connection
Response: 226 Transfer aborted


any ideas of what the issue might be or how to fix it?

The server is on the fritz. Reply codes starting with 2 mean success, yet the text sent by the server accompanying this success speaks of an error.

Contact your server administrator or server hosting provider and demand to have the server fixed.

this happens on several servers and only with filezille for the last 2 days. Other FTP programs work so it doesn't seem like a server related issue.
I haven't updated any of the setting of the filezilla before that. Probably just the latest update was installed - 3.41.2

And we still cannot do anything about it.

You are suffering from a network problem (maybe a firewall or bad routing blocking traffic, or a full server disk), and that, in turn, triggers a bug in the server where it returns an ambiguous, erroneous reply. The text of the reply suggests a transfer error, yet the reply code starts with a "2", meaning success. It would have to be a "4" (temporary failure) or "5" (permanent failure). Software like FileZilla cannot read and interpret text, that's for humans only. So, it has to rely on the reply code, as sole option. With the correct reply code 426, it would have automatically retried the transfer.

Hello,

I have a similar problem with latest Filezilla on Mac OS High Sierra. Small files will end up empty on the server while larger files, approx. 500 K or more, will upload fine. I have tested uploading the failing files to a number of different servers with the same negative result so it can't be a server issue. This is an example:

Status: Starting upload of /../xxyy.jpg
Status: Retrieving directory listing of "/../"
Status: Skipping upload of /../xxyy.jpg
Status: File transfer successful, transferred 508 bytes in 2 seconds
Status: Starting upload of /../xxyy.jpg
Command: PASV
Response: 227 Entering Passive Mode (212,97,132,120,250,135).
Command: STOR xxyy.jpg
Response: 150 Opening BINARY mode data connection for xxyy.jpg
Response: 450 Transfer aborted. Link to file server lost
Error: File transfer failed

Any help would be highly appreciated!
