Can you connect from WinSCP GUI? If you can, please post session log both from GUI and the script.
If not, please post log from aws commandline showing a successful connection (and WinSCP script log).

After I try swap -rawsettings S3UrlStyle=1 before -certificate=""12:34:66:66:66:66:66:66:99:3f:75:3d:66:6b:fe:25:76:66:8d:44:88:38:0c:a7:9e:e7:7a:8f:05:76:19:85"" It's working. I can manage files on S3 bucket now. Thanks

open s3://AKIAXXXXXXXXXXXXX:SECRETKEY@vpce-0dc3564fffda19bb6-ds1wt9rx.s3.ap-southeast-1.vpce.amazonaws.com/ -rawsettings S3UrlStyle=1 -certificate=""12:34:66:66:66:66:66:66:99:3f:75:3d:66:6b:fe:25:76:66:8d:44:88:38:0c:a7:9e:e7:7a:8f:05:76:19:85""

The order shouldn't matter in general. But, if you have the open command in an actual script file (not on WinSCP commandline in a batch file), the problem might be the double double-quotes. It should be just:

-certificate="12:34:66:66:66:66:66:66:..."

The command is probably broken after the double double-quote. The script might work even with brokent -certificate, if the certificate is cached already (from GUI) and if you are not isolating the script from the GUI configuration (what you should do to make the script portable).
