Onedrive sync error: ETag does not match

Hi,
I am trying to backup my Ubuntu 16.04 machine using rclone to onedrive (with encryption in between).
I am using the following rclone command:
rclone sync / secret:current --transfers 4 --checkers 8 --backup-dir secret:old/date +%Y-%m-%d --log-level DEBUG --exclude “/dev/” --exclude “/lost+found/” --exclude “/media” --exclude “/mnt/” --exclude “/proc/” --exclude “/run/” --exclude “/srv/” --exclude “/sys/” --exclude “/tmp/” --exclude “/var/” --stats-log-level NOTICE 2>>/root/backup.txt

but getting everytime errors. Here the latest output of the latest run (only the last few lines- if you need more no problem):

Do you have an idea what happens there?

Thanks and Kind Regards,

Can you grep the log for that and paste the line which it was in?
