Uploading a batch of PDF files one of them get us an error:

ERROR:
"Using TLSv1.2, cipher TLSv1/SSLv3: ECDHE-RSA-AES256-GCM-SHA384, 2048 bit RSA, ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=RSA Enc=AESGCM(256) Mac=AEAD
Copying files to remote side failed.
Failure reading network stream."

We've tried this:
1 - Zip the file => This works
2 - Change the name of the file: => Doesn't work
3 - Edit connection -> Advanced -> Connection -> TLS/SSL -> Maximun TLS/SSL Version set on 1.0 => This works

Can you download the .pdf using any other FTPS client, like FileZilla?

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Yes, I can upload and download all files with all clientes (Filezilla, CyberDuck).
Where is the session log?

Sorry, I didn't see that.

I'm not using winscp server, I'm using vsftpd. I attach the log from there. Also I'm attaching a pic of the error.

Sorry, but I was asking for WinSCP log file.
FileZilla or CyberDuck (verbose) log file would help too, for comparison.

Can we see a corresponding verbose log files of the other FTP clients?

Is it always this one particular file? Is the problem consistent? Can we get a copy of the file?

Hi Martín,

Uploaded perfect with FileZila, and both files.

Both works perfect with maximum TLS 1.1 and fails with maximum TLS 1.2.

I cannot reproduce the problem using the same encryption algorithms.

The FileZilla log does not contain any information about encryption algorithms. Would it, if you set higher logging level?

Any reason you are using implicit TLS/SSL encryption? Did you try explicit?
