I see this problem with hetzner storage box.
tl;dr The bug was introduced between rclone 1.53 and 1.55
config section:
[stobox-ftp]
type = ftp
host = XXX.your-storagebox.de
user = XXX
pass = XXX
explicit_tls = true
[stobox-sftp]
type = sftp
host = XXX.your-storagebox.de
user = XXX
pass = XXX
SFTP works fine:
rclone copy ./file_60mb.bin stobox-sftp:
FTP with explicit TLS fails for me:
rclone copy ./file_60mb.bin stobox-ftp:
I did not try pure FTP for security. According to reports above it should work fine.
Failure log with verbose dump:

Final error message:

Failing rclone versions: 1.55.1, git master
However rclone version 1.52.3 works fine.
I did not try other versions in between.
Will do git bisect later.
