I am in the exact same situation. I am a server at scaleway trying to sync to my amazon us account. Everything works fine when I sync to my google drive account.
the main error I see, which happens before the upload even starts:
2017/03/23 01:32:03 DEBUG : Supergirl/Season 2/Supergirl.S02E16.Star-Crossed (1).WEBDL-720p.mkv: Upload error detected but didn't finish upload: Post https://content-na.drive.amazonaws.com/cdproxy/nodes?suppress=deduplication: remote error: tls: bad record MAC ("HTTP status UNKNOWN")
I change my Scalway from Cloud to bare metal. Now i successfull sync 709 files (amazon_us --> amazon.de) only 2 error. (2 error files only resync automatically, second times it was sync without error)
I use this sync script, with “repeat every 1 min” Cron.
#!/bin/bash
#Exit script if its already running
if pidof -o %PPID -x "$0"; then
exit 1
fi
# Copy ACD_US with ACD DE
/usr/bin/rclone sync Secret_us: Secret_de: -v --log-file=/root/log/sync_log
exit
