On macOS SFTP via Synology VPN - SFTP command line works, FileZilla Works - Cyberduck does not.

[codethought]

Subject says it all. Trying to troubleshoot the connection from Cyberduck now for my own edification and perhaps to see if there is a bug (not likely) in Cyberduck.

SSH to the server on the VPN works.
SFTP to the server on the VPN works.
Cyberduck could not connect and hung requiring a force quit.

Can someone tell me how to gather logs in Cyberduck so I can look into what might be the issue?

Thanks.

Refer to the documentation to collect log files.

Thank you.. I'll do that and follow up!

@dkocher - see attached. Nothing immediately jumps out at me other than timeout references. Thanks.

Cyberduck tries to perform a TCP connection to your SFTP server over IPv4 on port 7434 and fails, can you confirm that the Synology SSH server is configured to use port 7434?

[codethought]

Connecting via SSH to servers in the network that are using that port works without issue.

We are effectively performing a nc -4 hostname 22 / nc -6 hostname 22 before trying to access the server, with the SSH alias resolved to any HostName.

Is your ~/.ssh/config only

Host *
  IdentityFile ~/.ssh/id_rsa

Do all addresses returned from dns-sd -Gv4v6 hostname reply to the above nc IP 7434?

Ah one thing, can you check in "Privacy & Security", in the "Local Network" category, that Cyberduck is enabled there?
