 Hi Team,

 I have been trying to set up S3 authentication using setup guide
 (https://trac.cyberduck.io/wiki/help/en/howto/s3) in Windows environment.
 I had set up the aws config file in c:/Users/<username>/.aws/credentials
 and gave the profile which is generated by AWS STS to Cyberduck bookmark
 downloaded form location: (
 ) but when I enter to connect to S3, I don't get any response and it says
 connecting but it doesn't connects. I have question that does this
 bookmark made for AWS STS temporary credentials works for Windows  or not.
 As I am seeing this bookmark takes the credentials from directory
 (~/.aws/credentials ) which is a Linux/MAC formatted structure. If this is
 the case, Do we have any alternative solution for connecting with temp
 tokens/MFA to AWS S3 using Cyberduck in Windows environment.

 Thanks and Regards,
 Vikram Mandal
