I am copying a tar file from my FSx server on AWS to my S3 bucket and although the system reports the copy successful and the data seems there, if I look from a different workstation (a local mac in this case), there are zero bytes copied.

Only when I disconnect from mountainduck is the data released and appears on the S3 bucket.

I don't know if has to do with any particular setting but this is highly disturbing as you can imagine.

My configuration is

Windows instance on AWS, FSX server and regular S3 bucket. I do have permissions and all that obviously.

In terms of mountainduck settings..

Smart Sync is off (I am on Online mode)
No proxies
Enable cache is ON

AWS S3 settings
region EU london (eu-west-2)

Using Windows10 Pro
