Currently, on Windows 10 with current patches, when I try to open a connection with aws_access_key_id and aws_secret_access_key defined, nothing happens when I click on "Connect". Same functionality both on the latest 6.x as well as the latest 7.x beta. The same credentials work normally from the same Windows system using Cloudberry Explorer for S3, and the operation works also normally with the Mac version of Cyberduck (on a Mac, naturally :-), so it seems the Windows version of Cyberduck is affected by this problem.
