Microsoft Windows Server 2019 Datacenter Version 10.0.17763.2237 on Amazon EC2
I can connect to S3 and copy small files.
The issue starts when I copy a big file for more than an hour. I got a warning (attached) from WinSCP about the server's certificate is not known. I press "Yes" to continue connecting and store the certificate but the warning came again and again. As result, I cant copy big file overnight.
