ERROR: Connection timed out after 20 seconds of inactivity

Hi

I am using CWP 7, and when I use the FTP I have this error:

Connection timed out after 20 seconds of inactivity

I think it is about the TLS but I don't know how to fix it.

I want to solve it in the server.  Can you help me?

i have the same problem, can anyone help

Try editing /etc/pure-ftp/pure-ftpd.conf
find  # PassivePortRange             30000 50000
and uncomment it.   Open those ports in CSF

I just did a whole day of research on this. It happens when your FTP client is set to "Explicit FTP over TLS".

Editing # PassivePortRange and opening those ports in CSF /etc/pure-ftp/pure-ftpd.conf works.

If you don't have time, as a temporary solution you can also set your FTP client to plain FTP (Insecure).

Having the same issue

Already done enabling the passive ports in csf and pureftp.conf no luck again same issue.

only works with plain authentication in file zilla
implicit over tls or explicit over tls
does not work

tried everything in cwp forum no luck
if any one got the solution pls post the steps
