Could this be related to the transfer speed dropdown?
Although I like WinSCP very much it seems to disconnect and reconnect for me every 15 seconds as other posts have noted.
I found that, oddly, if I clicked the speed limiter dropdown and left it down, the disconnections didn't happen at all. However the transfer speed slowly dropped away to a couple of hundred bytes/sec.
I hope that may offer some kind of clue as to what is happening...ahh, maybe it is just that selecting the speed limiter pauses the transfers altogether...back to the drawing board.
OK so when all else fails read the manuals...
as mentioned in this post https://winscp.net/eng/docs/message_disconnected it seems to have totally solved the issue - running the two command lines at the bottom of this page:
https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd421710(v=ws.10)
did the trick. Hasn't stopped since.
