[HELP] Download file with SFTP failed - action failed (6)

I’m trying to download file from my computer using SFTP. My computer already SSH service running, so I’m successfully connected using SSH from another device.

So, I want to download file to my MikroTik using this terminal command:

/tool fetch url="sftp://192.168.99.2/usr/share/ca-certificates/trust-source/mozilla.trust.p11-kit" user=root password="pass"
  status: downloading

  downloaded: 588KiB
       total: 950KiB
    duration: 3s

I can see the progress when downloading, but then, it’s failed.

/tool fetch url="sftp://192.168.99.2/usr/share/ca-certificates/trust-source/mozilla.trust.p11-kit" user=root password="pass"
 status: failed


action failed (6)

Note: upload is working, if I upload my router backup file to my computer using SFTP is working.

Please help, what could it be wrong? Thank you in advance.

Fetch with https is working, the file downloaded. But with SFTP not work.
Please help…
