Issue with WinSCP Connection to Smart-1: SFTP Packet Size Error

[IGSSV]

Hello Check Point Community,

I am experiencing an issue when trying to connect to my Smart-1 appliance using WinSCP. The following error message is displayed, preventing me from uploading files:

Received too large (1129072974 B) SFTP packet. Max supported packet size is 1024000 B.
The error is typically caused by a message printed from a startup script (like .profile). The message may start with "CLIN".
Cannot initialize SFTP protocol. Is the host running an SFTP server?

Environment Information:

WinSCP Version: 6.3.4
Smart-1 Device: R81.20 VM

Has anyone encountered this problem before? Any suggestions on how to resolve this would be greatly appreciated.
