Hello @TtheBC01 ,
Welcome to the forum!
@nerdatwork the rclone will not allow you to delete non-empty buckets too, and since the encryption key is lost, this bucket will looks like empty, but it’s not true - the current encryption key just unable to decrypt a content.
The working solution would be only to use uplink CLI.
To list buckets:
uplink ls
To remove a bucket even if you lost an encryption key:
uplink rb --force sj://bucket-to-remove
