Monitoring error when changing the pure-FTPd port

Hi!

For security reasons, I'm changing the port to FTP. After changing the port, the FTP server is running, but Monitor (Server State) returns an error.
Error: One or more needed services are offline [More...] => FTP-Server: "Offline"

How can I change the FTP listening port for Monitoring so that there is no error?

Server:
- Ubuntu 22.04.3 LTS (Jammy Jellyfish))
- ISPConfig 3.2.11p1
- Pure-FTPd

Thank you in advance for your help.

 

Everything is clear
Thanks for the quick response.
