WinSCP Network Error: Software Caused Connection Abort - Fix

Addressing Frequent Disconnections in WinSCP

For Windows users, WinSCP stands out as the premier SCP/SFTP client. However, its default configuration lacks a keepalive function, leading to frequent disconnections.

Maintaining an open client during work is a common practice, but this can disrupt workflow due to these interruptions.

It's crucial to prioritize security; if you're still utilizing standard, insecure FTP for file transfers, transitioning to SCP or SFTP is highly recommended.

Configuring Keepalive Settings

To resolve the disconnection issue, adjustments must be made to your saved connections within the WinSCP Login screen.

Navigate to "Connection" in the left-hand treeview. Then, modify the "Keepalives" radio button selection.

Choose the option "Executing dummy protocol commands" to enable keepalive functionality.

Alternatively, the "Sending of null SSH packets" option is available. However, compatibility isn't guaranteed across all servers.

Selecting "Executing dummy protocol commands" ensures broader server support and eliminates the unwanted error message.

Finalizing the Changes

After making the desired adjustments, remember to click the "Save" button to apply the new settings.

By implementing this change, you can enjoy a more stable and uninterrupted file transfer experience with WinSCP.
