MT4 Publisher Passive mode issue?

Yesterday, I faced the problem. MetaTrader publisher didn't work regular mode. (Correct settings). However, it started to work when I turned on passive mode.

What is a passive mode? And What is the difference?

The following is from help which details the difference. In short what it means is that the FTP server can be configured in 2 ways and you have to choose the right way for your server's configuration. One way to determine this by using an FTP client like FileZilla and watching the connection log. Or you try both and find the one that works. Once you find what works, don't change unless you have to use another FTP server.

Passive mode — switch between active and passive mode of data transfer.
In active mode, a free port (from dynamic range of 1024 to 65535) is allotted in the client terminal to which the server will connect in order to set connection for transferring of data. The FTP server connects to the client's port with the given number using TCP port 20 from its part to transfer data. In passive mode, the server informs the client about the TCP port number (from the dynamic range of 1024 to 65535) to which the client can connect to set up data transfer.

The main difference between active and passive FTP mode is the part that opens connection for data transferring. In active mode, it is the client who has to accept connection from the FTP server. In passive mode, the client initiates connection, and the server accepts it.
