Reboot needed after each Let's Encrypt renewal

Your highnesses: Freepbx’s Cert Manager states all is well, yet:

openssl s_client -connect [host]:5061 < /dev/null | openssl x509 -noout -text

reports otherwise… Not even

fwconsole restart

fixes things, only an unpopular, hard reboot.

What might that be?

What about running systemctl restart httpd?

Good idea, but it seems to be an issue on port 5061 which apache is not configured to answer to.
