Issue with intermittent SFTP connection drops during large file transfers
Hello everyone,
I’ve been using WinSCP for a while to transfer files over SFTP, but recently I’ve been running into an issue where the connection randomly drops during larger transfers.
This doesn’t happen with small files, but when I try to upload or sync folders with many files or larger sizes, the session sometimes disconnects midway. I then have to reconnect and restart the transfer.
My setup:
WinSCP latest version
SFTP protocol (SSH)
Windows 10
Stable internet connection (no issues in other apps)
What I’ve tried so far:
Enabling “Keepalives”
Increasing timeout settings
Switching between “Optimize connection buffer size” options
Using both Commander and Explorer interface modes
None of these fully solved the issue.
Has anyone experienced something similar? Could this be related to server-side limits, or is there a recommended configuration in WinSCP for more stable large transfers?
Any advice or suggestions would be greatly appreciated.
Thank you in advance!
