Transfer fails with 421 Too many connections (8) from this IP

[cyberduck]

6b35ebc created the issue

When trying to upload files via FTP, I can establish a connection but when I try to upload the Drupal files the connection is dropped. Contacted my hosting service, MacHighway, about this. They indicated that they had made some changes to server, so I deleted the bookmark and created a brand new connection. In their testing they were able to transfer using FileZilla, which I also ended up using to update all my Drupal sites. I much prefer Cyberduck. Please advise.

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?
