I configured WinSCP to connect to a local S3 bucket.
The local server does not have a valid certificate and so this message comes up.
The server's certificate is not known. You have no guarantee that the server is the computer you think it is.
Server's certificate details [...]
Fingerprint (SHA-1): 12:34:56...
Summary: Certificate was not issued for this server. You might be connecting to a server that is pretending to be "someone".
If you trust this certificate, press Yes. To connect without storing certificate, press No. To abandon the connection press Cancel.
I press yes and the message comes up again. It comes up on each remote operation at least once.
What can I do to prevent WinSCP from showing this message?
