Lost Connection (Timeout detected, (data connection))

Hi
Since yesterday I have no access to one of the FTP services through the WinSCP app and I encounter this error. I'll send the log file as well. Please give me some guidance.
It should be noted that I connect through the command prompt without any problems.

Regards,
Mahdi

The problem is not with (control) connection, but with directory listing (data connection).
Can you list the directory "through the command prompt"? Btw, what command prompt? The Windows legacy ftp client?

But I connect with CuteFTP without any problems. I'll send you the log. Since WinSCP is on the company's authorized list of software and we are not allowed to install another program. Please check again and if possible, take action to resolve the issue.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Hi,
Have you been able to find and fix the problem? We still have problems and do not have the ability to connect to some servers via FTP using the WinSCP app. While we have no problems with other programs.

I have asked you for log files. You didn't provide them yet.
