FTP sync not deleting files / directories because of IO errors

Hi everyone!
rclone does not delete any files / directories because of IO errors.
The only errors shown in the log (even with -vv) are "connection time out" even with 20minutes "contimeout". Does anyone has an idea how i can fix that? There are just a few errors out of over 200.000 checked / copied files.

Thanks a lot!

What is the problem you are having with rclone?

2020/10/15 18:46:06 ERROR : Local file system at /mnt/disk4/backup: not deleting files as there were IO errors

What is your rclone version (output from rclone version)

rclone v1.53.1

  • os/arch: linux/amd64
  • go version: go1.15

Which OS you are using and how many bits (eg Windows 7, 64 bit)

As App in UNRAID 6.8.3

Which cloud storage system are you using? (eg Google Drive)

FTP to a webhosting server

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone sync C4-LI: /mnt/disk4/backup --contimeout=20m 2> /mnt/disk4/backup/backup.log

The rclone config contents with secrets removed.

[C4-LI]
type = ftp
host = webhostingserver
user = user
pass = password
explicit_tls = true
concurrency = 5

A log from the command with the -vv flag

The log with -vv is over 200.000 lines long. So first just the normal log. I let it run on -vv but there are not more information than in the normal log as far as i can see.
