What is the problem you are having with rclone?

Loosing connection after a while when transfering files. Even when uploading few files I get I/O errors.
Upload is initiated from local storage to FTP client.

While FTP is mounted and I see I/O errors popping up I tried to run rclone ls remote: command and it listed the files but transfer was still halted.

Run the command 'rclone version' and share the full output of the command.

rclone v1.62.2

  • os/version: redhat 8.8 (64 bit)
  • os/kernel: 4.18.0-477.15.1.el8_8.x86_64 (x86_64)
  • os/type: linux
  • os/arch: amd64
  • go/version: go1.20.2
  • go/linking: static
  • go/tags: none

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

FTP

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

rclone mount remote:/Dir/ --allow-other --file-perms 0666 --dir-perms 0777

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

welcome to the forum,

--- what other ftp clients have you tested, filezilla, lftp or what?
--- can update rclone to latest using rclone selfupdate
--- might try to tweak --ftp-close-timeout
--- might try --dump headers
--- does the server offer sftp as rclone has better support for that?
--- might better to test using simple command such as rclone copy instead of rclone mount.
--- post a full debug, not a small snippet.
