Unable to MFA Auth to AWS S3 service

Hi Team,

I have been trying to set up S3 authentication using setup guide ( 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
