I think, CA bundle is missing from the SSL Certificate, can you check your SSL here  https://www.sslshopper.com/ and confirm?

This is not certifate problem.
As I see there is no configuration for TLS in FTP config file.
This should be fixed by CWP developers.

really
restart FTP is the answer from CWP staff ?

Can You tell me how restart could add missed configuration ?

As I can see for example here:
https://www.howtoforge.com/tutorial/pureftpd-tls-on-centos/

there is no
CertFile             
option in orginal config file pure-ftpd.conf on CWP panel

I found some info about PureFtp TLS and  Let'sEncrypt:

restart command will show you error message so its the place where to start when searching for issue.

if this is certificate related you can try to save your hostname again, it should generate required certificates.

Same problem here, any fix for it? FTP only, SFTP works fine.

EDIT:  Ok, this helps. But that shouldn't be fix for CWP's problems.

I followed the tutorial here: https://www.howtoforge.com/tutorial/pureftpd-tls-on-centos/ and it worked for me.

You do need to edit the firewall configuration to add 30000:50000 to the TCP port range to prevent the firewall from locking you out:

Go to Security > CSF Firewall and click the button to 'Edit Configuration File'. Find:
Code: [Select]
# Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,2030,2031,2082,2083,2086,2087,2095,2096"
 
# Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,53,80,110,113,443,2030,2031,2082,2083,2086,2087,2095,2096,587,993,995"

and add 30000:50000 to to both lines

No, it isn't using the Letsencrypt SSL certificate, but so what ?  You can 'Require explicit FTP over TLS' and the files will transfer securely. The SSL certificate generated by following the tutorial is valid for 20 years, so your server is likely to be obsolete well before the certificate expires.

I do take the point that this is a fundamental requirement for FTP and it would be better if CWP automatically accommodated it, but for the price I've paid ($10 pa for CWP Pro), I'm not complaining. Last time I looked, cPanel was $200 PER YEAR !!
