Getting error connectex: No connection could be made because the target machine actively refused it

thanks for the reply, but this is not a firewall issue, nothing is blocking the outbound connection.

for some reason, when using 'sync' with '--backup-dir', rclone does not seem to simple move the file from the main folder to the archive sub folder. both folders are in the same bucket.

there is a huge delay and the progress displays the following.
'Checking:

  • ABJ_HOMESERVER01_BOOKS.-06-30T100018_C269.vib: checking
    Transferring:RVER01_BOOKS.-07-30T100026_1C41.vib: checking
  • ABJ_HOMESERVER01_BOOKS.-06-30T100018_C269.vib: transferring
    "
    i am confused as why and for what reason rclone needs to check a file and not simple move the file from one folder to another subfolder inside the same bucket.
    if the file to be moved is large, like 65GB, the log is full of errors such as
    "2019/08/16 19:51:54 DEBUG : pacer: low level retry 1/10 (error RequestError: send request failed

    and
