Unable to access to FTP via Windows11

Hello,

After upgrading by 'elevate-cpanel', Windows10 can access to ftp server, however, Windows11 cannot access. Pure-FTPd server and CSF is equipped.

I read the reference site.

https://docs.cpanel.net/knowledge-base/ftp/how-to-enable-ftp-passive-mode/

It mentions as follows.

Add the desired changes to the file. If your FTP server exists behind a NAT configuration, set the ForcePassiveIP option to the FTP server’s public IP address, as in the following example:
ForcePassiveIP: 203.0.113.0

If your server does not exist in a NAT configuration, set the `ForcePassiveIP` option to the following entry:
ForcePassiveIP: ~

How can I check whether the server exists behind a NAT configuration?

I checked '/var/cpanel/conf/pureftpd/main' file, and confirmed that passive ports 49152 through 65534 for Pure-FTPd server was enabled.

[root@server ~]# less /var/cpanel/conf/pureftpd/main

---

PassivePortRange: 49152 65534

---

Does '49152 through 65534' mean, 49152 port and 65534 port or, from 49152 to 65534?

so in CSF, is it 49152:65534 at TCP_IN at 'Firewall Configurtion > IPv4 Port Settings'?

Currently, 49152:65534 at TCP_IN is not configured at CSF TCP_IN, however, Widows10 can access to ftp, only Windows11 cannot access to ftp.

Any advice would be appreciated.

  it's from 49152 to 65534

  Add 49152:65534 to TCP_IN, and if your server uses IPv6 add the same to TCP6_IN

  Sorry for the late reply. I did the above setting and restarted csf.

  After upgrading by 'elevate-cpanel', windows11 could connect to the ftp server itself now, however, it still cannot get a file list. The server indicates the only '/' like the image.

  

   

  No folder like 'public_html' does not appear. With this condition, when uploading any files, the server reponds 'Error 10060'.

  Is there any countermeasure?

  cPanel version is 120.0.5.

  Thank you.

  I'd think this a firewall issue.

  Disable csf in the server, if it still does not work then the problem is most likely with Windows computer's firewall.

  I cannot disable csf because it is too riskey. I'm looking for a way to deal with this by adjusting the CSF.

  Thank you.

  You wouldn't permanently disable CSF - just for a short time to perform your test to rule that out as the issue.
