FTP Issue - Cannot create files


Hey all,

Quick question regarding FTP deployment. We’re deploying a site to two remote servers with FTP setup. One is working fine, however the other is getting an error:

Server validation failed: org.apache.commons.net.ftp.FTPConnectionClosedException: FTP response 421 received. Server closed connection.

When trying to write files. It is successfully creating the directories and removing the test directory when testing the action, however it can never upload.

We can connect and write files using the same credentials from my local PC so it doesn’t look like a permissions issue at the Filezilla level. Could it be that we need to do something with the IP addresses for Buddy? If so how does it connect, create folders, but cannot write files?

Am I missing something really obvious?

Server is running on an Azure Virtual Machine, Windows Server 2012

Thanks in advance.
