The provider should check the support for data connections using PASV.

Contacted provider, MacHighway, and they made sure that PASV mode was enabled on their server. The same problem persists – I am able to connect but when I try to upload files using FTP, there server drops the connection.

Since I can use FileZilla to upload files, it would seem that the issue is with CyberDuck. Please advise.

Could not post log here as it was too many characters. So I attached it as a rtf file.

Please limit the number of connections allowed for file transfers or disable the use of multiple connections for file transfers in Preferences → Transfers → Transfer Files by choosing Open new connection.

The problem had been resolved. Why did you reopen? Is there something I need to do?
