Copy SSL to ProFTPD

OS type and version RHEL 9.1
Virtualmin version 7.7-Pro

Long story short, I changed my server hostname.
How do I copy SSL certificate from virtual server to ProFTPd SSL? I went to the “SSL Certificate” option under the virtual server, clicked “Copy to services/set default for services” and it did copy it to Dovecot, Posfix, Webmin, Usermin, but not the FTP server. Filezilla reports the previous hostname of the server.
