filesystem-nio2 PutObject https response error 501 (Not Implemented) with rclone #816
Description
I'm trying to configure S3Proxy on Windows with Windows UNC/SMB path as backend.
Each file upload return 501, but files are properly stored on SMB location.
Am I missing some configuration part, or is rclone not compatybile with filesystem-nio2? (With filesystem provider there is no issue with this operation).
Some dubug logs from rclone:
