Cannot sync with vsftpd linux from windows ntfs

[aminvakil]

I don't know if anything I say is related to this issue or not, but:

Client is FreeFileSync 10.24.

Ftp Server is vsftpd: version 3.0.3.

vsftpd configuration: https://github.com/aminvakil/docker-alpine-ftp-server-tls/blob/master/vsftpd.conf_noreusessl (I've created this docker image (noreusessl) to test if this works or not, but it wasn't successful too)

Also I run vsftpd using this:

/usr/sbin/vsftpd -opasv_min_port=21000 -opasv_max_port=21010 ftp.example.com /etc/vsftpd/vsftpd.conf

Also some files with zero size (empty txt) and 1,510 Kb (SyncSettings.ffs_batch) can be transferred successfully, but anything else (1MB, 25MB, etc.) gives me this error:

CURLE_PARTIAL_FILE: server did not report OK, got 426
426 Failure reading network stream. [curl_easy_perform]

I can successfully transfer the exact file with FileZilla to ftp server, but the problem exists in freefilesync.

Maybe it's related to curl.

Any help would be appreciated.

Is there some test server available that demonstrates this error?

Probably a server issue:

Thanks for your reply, yes most probably it seems to be a server issue or something with windows server 2016 which I don't have much experience with it.

Just wanted to ask if anyone else had this issue.

Unfortunately no, I've changed the infrastructure to a samba server for a couple of another reasons, but if I tested it somewhere else and figured out the solution I will add to this post.
