We noticed a problem when transferring a folder that has subfolders and some files. It's a full tree. When checking the log, everything is fine, it creates a folder, changes directory and starts transferring the file. But the file transfer freezes and the connection stops after 90 seconds. It doesn't show an error, it just does nothing.
does anybody have an idea about what tick I've missed? do I have to enable or disable a function? Might that be a firewall problem or a windows problem?
If we access wia ZileZilla or Cyberduck, there isn't a problem. It happens only from specific senders.
