Hi all,

I'm trying to setup a SFTP job with public key encryption using VisualCron 9.9.8 . But everytime I test the connection, i receive a connection time out error. I've had a chat with our infra team and they have advised that the traffic is enabled from our client to the external endpoint. Can someone please assist with this?

This is the error I receive when trying to connect via Connection Explorer:

SBSocket.EElSocketError: Connection timeout
at SBSocketClient.TElBaseSocketClient.DoMessageLoop(Boolean NoPeek)
at SBSimpleSftp.TElSimpleSFTPClient.Open()
at ctlRemoteBrowser.ConnectThread(Object connectionObject) in C:\git\code\VisualCron\Connections\ConnectionExplorer\ctlRemoteBrowser.vb:line 1605

Please note that I can connect to the SFTP endpoint via WinSCP.
Forum information
I use an SFTP task in several of my jobs, and use WinSCP as well. Not sure if any of this will help, but here's what I would check (sorry if some is obvious).

In the SSH Keys Global Object
  • Make sure you have the correct key pair imported (especially when changing between test/prod servers)
  • Verify key fingerprints
  • The PPK file should be the same file you use in WinSCP

In the Connection Global Object for the SFTP connection
  • Verify your protocol is set for SFTP in the Common Settings tab
  • Verify the Server Address ( and Port (22) in the Connection Settings/Main Settings tab, Server section
  • Verify the Authentication Type, User Name, and the correct private key is selected in the Connection Settings/Main Settings tab, Credentials section
  • For my connection, I did NOT need to change anything from the defaults on any other tab which you might (proxy, etc)
  • Go back to the Common Settings tab and click "Test"

  • Ask your network team to verify f/w rules for traffic permission
  • Ask the owner of the external server to verify f/w rules on their end as well (extra effort here as you may have a similar problem I did since we use an egress endpoint that NAT'd the VC server address we gave the vendor)
  • Ask network teams on BOTH ends to monitor live logs for packet refusals when you make an attempted connection (this is where we found out about the egress point IP translation)

Hope this helps!

If you are having trouble SFTPing in to your server, follow these steps one-by-one until your problem is resolved.

Make sure you log in to your server's IP ADDRESS (not your domain) with the SYSTEM USER used to create your app; attempting to connect to your domain directly is one of the most common causes of SFTP connection failures.
Make sure you attempt to connect over SFTP. ServerPilot does not support unsecure FTP connections.
Reset your system user password in ServerPilot.
Restart your SFTP client. This can reset any password caching your client might be performing.
Uninstall and then reinstall your client. This will clear any hidden caching done on your local machine.
Try to connect with a different SFTP client.
Attempt to SSH in to your server as SYSTEM_USER@IP_ADDRESS. If you are unable to connect to your server over SSH, then password authentication may have been disabled and you will need to enable it.
Attempt to connect through your provider's console. If you are unable to do so, this indicates an issue with your server that you will need to address with your provider.
