We are trying to send some txt files for tax reporting with FTP using the currently latest Winscp client (5.15.5), we do however get the "Lost Connection. Timeout detected. (control connection) Copying files to remote side failed".This happends when the transfer has reached like 99% and its only when transferring larger files (more then roughly 100mb). when reconnecting to the host server we can see that atleast half the file has been transferred. we have tried alot of things that people have recommended in the forums but nothing have helped.
we are running windows version 1809
Here are the log files
filetransfer starts at 10:43:06.287
Any help would be much appreciated.
