Can you connect with WinSCP GUI from the server?

Could you please let me know the step to follow, how to connect with WinSCP GUI from the server.

Note: I can able to connect the via username and Password, when double click on WinSCP.exe.

So please try the same, while running winscp.exe on the server.

I believe that WinSCP only supports Windows-based applications; it does not support web-based applications. No problems with the code, firewall, or privileges, in my opinion. We are unable to push files to SFTP once the code has been published on the web server, even though everything is functioning well locally (on the development workstation). Please let me know have you any idea about that.
