Automatic backup to an Azure server on ftp port

[vem]

Hello,

I am facing the following issue. I have configured an FTP server for the automatic backup. It was working fine ( both in the same network 10.10.x.x/16 . Now I did the same configuration on an Azure server , the ftp on default port 21 is working but the backup isn't transferred to the server. Any ideas? The connection on the Azure server is allow to that network 10.10.x.x/16. Maybe the port 21 is blocked on the checkpoint server? I am not the network admin, maybe I can check that with him, but any other ideas? 

Thank you !
