CWP Server FTP Connection Error

Hello,

I have a problem with my CWP7 server. I have been having problems accessing the system via ftp for almost a year. I use the auto-publish feature in my project that I am developing with Phpstorm. Thanks to this feature, the file is uploaded to the server as soon as I save it. The system is fine so far, but for some reason that I cannot understand what is happening on the server, neither the test connection works in the host definitions in Phpstorm nor can I upload the file when I save the file. I checked everything in the firewall settings, but the problem could not be solved. Whenever I log in to the CWP management page, all tests are successful and all files are sent. If anyone has an idea or knows a solution, can they share it?
