Jeff,
Normally when the FTP client is configured not to create more than 2 connections there are no IP blocking for FTP transfers. However not all FTP clients have explicit option to limit the number of connections. In most FTP clients this option is controlled by the amount of concurrent transfers. But this value in some specific case does not directly limit the amount of connections. The excessive amount of connections can also happen due to peculiarities of clients internet connection.
As far as we can see in your particular case even though the FTP client was configured to 2 transfers the amount of connections from your IP to the server was constantly larger than 2. There is quite an array of reasons for this investigation of which takes time.
We understand that waiting in chats is frustrating. We are sorry it all took so long in your chat session but the supporter needed time to identify and localize the issue. As the result of the analysis performed by the supporter eventually he came up with a solution.
