pull: from SSH remote, does not follow ProxyJump in ~.ssh/config

Bug Report

Description

When an SSH remote needs to be reached via a ProxyJump connection, dvc pull cannot connect to it.

Reproduce

Set up ~/.ssh/config to allow connection to the server behind the proxy, example:

Host main
    ServerAliveInterval 60
    ServerAliveCountMax 10
    User memain
    HostName 1.2.3.4
    IdentityFile ~/.ssh/id_rsa
    ProxyJump [e-mail]

Test ssh from the terminal to check the ProxyJump and SSH keys for both proxy and main are working:

melocal@local:~$ ssh main
memain@main:~$ exit

Pull the git repo to the local machine. Set up a local remote with the full SSH URL

melocal@local:~/dvc_repo$ dvc remote add --local fromlocal ssh://memain@main:/path/to/dvc/remote
melocal@local:~/dvc_repo$ cat .dvc/config.local
[cache]
    dir = cache
['remote "fromlocal"']
    url = ssh://memain@main:/path/to/dvc/remote

Trying to pull from the remote gives an SSH connection error:

melocal@local:~$ dvc pull -r from local
ERROR: unexpected error - [Errno 61] Connect call failed ('1.2.3.4', 22)

Expected

DVC pulls the data from the remote.

Additional Information (if any):

The verbose output was really long, and I didn’t want to go through and anonymise it all, but I can do it later if needed.

Update!

I replaced proxyJump with ProxyCommand and now it works.

Host odm
    HostName 123.123.123.13
    User me
    IdentityFile ~/.ssh/id_rsa
    ProxyCommand ssh -W %h:%p bastion
    # ProxyJump bastion

@pwrightkcl Can you share the steps on Linux. I’m simply doing what they say https://dvc.org/doc/start/data-management.

I can push to a brand new dir on a server iff i don’t have to go through a proxyjump.
