In order to provide help to you a litte more information is required:

1. Which OS are you using CyberPanel with?
   
2. What is the FTP server that was installed with CyberPanel or which FTP server have you installed (if you installed it manually)?
   
3. Have you checked the FTP server logs for errors (error logs are usually in /var/log)?
   
4. Have you changed any configurations that belong to CyberPanel, the FTP server and all its services? If yes, what exactly did you do?
   

It would be great if you could answer the questions above and provide more information by doing so.

Thank you.
