S3 Assume Role only works on Cyberduck and S3 Browser

Hi, does anyone have troubleshooting tips for figuring out why I can only get an assume role connection on Cyberduck and S3 Browser?

It's your typical Assume Role configuration. The S3 Browser app connection only works if I've unchecked "List all my buckets" on the source account and the assume role account.

Thanks for your sharing your expertise.

I should have mentioned, WinSCP is throwing a permissions error in the logs.

The role only has write permissions to bucket.
