    Hi there,

    After I added Public IP address I get the following Error in filezilla:

    Status: Disconnected from server
    Status: Resolving address of host.abc.com
    Status: Connecting to xx.xx.xx.xx:21...
    Status: Connection established, waiting for welcome message...
    Status: Initializing TLS...
    Status: Verifying certificate...
    Status: TLS connection established.
    Status: Logged in
    Status: Retrieving directory listing...
    Command: PWD
    Response: 257 "/" is the current directory
    Command: TYPE I
    Response: 200 Type set to I
    Command: PASV
    Response: 227 Entering Passive Mode (xx.xx.xx.xx,157,197).
    Command: MLSD
    Error: Connection timed out after 20 seconds of inactivity
    Error: Failed to retrieve directory listing

    The above example is set in 50-plesk.conf.

    If I remove Public IP, it works again.

    Any ideas on why it fails with Public IP set?

    hi @Glenn,

    If your server is behind NAT and the public IP is added in Tools & Settings > IP addresses in Plesk, the issue may be caused by incorrect firewall configuration on NAT (Misconfigured routing/external Firewall settings). To solve this, firewall should be configured properly by the hosting provider (server owner). Alternatively, public IP should be removed from Tools & Settings > IP Addresses menu.
