Password-free ssh authentication had been set.
There is a file /home/test.txt in my remote_ip.

vim scp://root@remote_ip//home/test.txt

Why vim scp can't read file on my remote vps?

vim  --version
VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Sep 30 2017 18:21:38)
ls -al   /home/test.txt
-rw-r--r-- 1 root root 100 Apr 23 12:40 /home/test.txt
enough space left on both local and remote device.
ssh credential established between my vps and local pc.

To connect with my vps.

ssh  -i .ssh/id_rsa  -p 1000  root@remote_ip

The port number is 1000 not standard 22.

    Without any information at all it will be extremely hard to give any meaningful answer to this. Basically your question is just "it doesn't work". Okay ... but what are the results? What are your settings? etc Even with all information, this is a very difficult problem to solve over the internet, as there are just so many variables involved. your best bet is really to look at the ssh logs etc. yourself and debug from there.

Okay, I'm blind shooting here, but here are some ideas

  • You have older vim version than 6.
  • The remote file is not readable
  • No space left on the local device.
  • Local firewall blocks the outgoing connection
  • Remote firewall blocks the connection
  • Your ssh public key is not in the authorized_keys file on remote
  • Your local ssh keys are not in the default folder .ssh

You may want to debug your ssh connection first with ssh xy@remote -vvv to find out if the connection can be established.

  • Connection can be established with ssh -i .ssh/id_rsa -p 1000 root@remote_ip

    @it_is_a_literature do you specify the port? You can create an entry in ~/.ssh/config, use vim scp://root@remote_ip:1000//home/test.txt or let g:netrw_scp_cmd="scp -q -P 1000".
