DVC ssh error. [Errno 111] Connect call failed

Questions
1

Hi,
When I tried to download one file through dvc using ssh from my Mac, it has steps and error as below. It seems connection issue from my Mac to server, but I can ssh or sftp to the server from my Mac. It works for “dvc pull” if I set up the local repo on server and remote repo on the same server not using ssh. “dvc remote add -d myremote /mypath/dvcstore”. I follow this doc: SSH & SFTP

I also tried create a local repo on the server, set up “dvc remote add -d myremote ssh://myusername@server:2222/mypath/dvcstore”. It get the same error as below.
I’m stuck for several days, really appreciate your help!

pip install dvc_ssh
dvc remote add -d myremote ssh://myusername@server:2222/mypath/dvcstore
Setting ‘myremote’ as a default remote

dvc pull dir_test
ERROR: unexpected error - Multiple exceptions: [Errno 111] Connect call failed (‘10.68..’, 2222), [Errno 111] Connect call failed (‘10.68..’, 2222)

Are you behind some firewall by chance, proxy?

Could you also check if you have some specific settings in your .ssh/config - could you share it please?

Also, are you using SSH keys a way to do auth?

Also, please share the dvc pull -v dir_test

Thanks.

Update:

  1. fixed for local repo on the same server as the remote server. Need to remove the port number 2222 and it works: “dvc remote add -d myremote ssh://myusername@server:/mypath/dvcstore”
  2. local repo on my Mac still has error connecting to remote server.
    I remove the port number and use the same one as in 1). My Mac firewall is active. I followed thoese steps in this doc
    SSH remote: unexpected error - Permission denied
    dvc remote modify --local myremote password YOUR_ASSPHRASE
    However, it still ask me for ssh key passphrase when dvc pull. I checked the passphrase is correct. Also test for dvc pull a single file, same error.
