Do I understand right, that it's a single file that takes so long to download, correct?
Can you download the same file using any other FTP client?
Thanks for your response.
1) Yes, only one file is large and takes more time to be transferred.
2) I did the test you asked for. I installed FileZilla and the file was completely downloaded without interruption or login request.
But by analyzing the log, I noticed that the connection is lost during the download (20 minutes later):
2018-07-30 17:45:45 4352 3 Command: RETR VW23x_VL_P7000_I15.vmdk

The complete log file is attached.
Despite the error, Filezilla does not request a login again and does not lose the download. But I prefer the WinSCP interface.
I've tested several downloads. Always occurs "421 timeout / Connection closed by server" after 20 minutes of transfer via Internet. The problem does not occur on the internal network. I do not know how to solve this. Can you help me?
Thanks in advance.
