Read FTP server from app Hosted in Azure

Question

I am trying to connect my app to read a document hosted in my FTP server, I am using FileZilla, my app is hosted in Azure. But it seems it cannot connected. I have a public IP, in localhost my app runs fine but when it's online it failed. This is the code I am using to connect the app with my FTP server.

public static void getExcelFromFTP(string destinationFile)
    {

        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(@"ftp://100.100.100.0/folder/file.xlsx");

        request.KeepAlive = true;
        request.UseBinary = true;

        request.Credentials = new NetworkCredential(@"username", "password");//FTP Server credentials
        request.Method = WebRequestMethods.Ftp.DownloadFile;




        Stream reader = request.GetResponse().GetResponseStream();
        FileStream fileStream = new FileStream(destinationFile, FileMode.Create);

        int bytesRead = 0;
        byte[] buffer = new byte[2048];
        while (true)
        {
            bytesRead = reader.Read(buffer, 0, buffer.Length);

            if (bytesRead == 0)
                break;

            fileStream.Write(buffer, 0, bytesRead);
        }
        fileStream.Close();

    }

Can somebody help me out with this issue? Thanks in advance.
