Thanks Joe. I believe  
a) it is the particular location of the SSL within Webmin/Virtualmin that is leading tor the error, , i.e I’m simply using the wrong SSL, as per [discussion on location](https://forum.virtualmin.com/t/slightly-confused-about-ssl-files-and-their-locations/104459)  
b) or APACHE2 is not seeing the new mosquito SSL and needs integration

in particular, i’m not sure if the ca.key and ca.crt is from /etc/ssl/virtualmin/domain/, or elsewhere…  
as whilst the client cert builds ok, it cannot be found, hence its a webmin + Apache2 issue

errors including: ‘Error: Unable to load client certificate “/etc/mosquitto/certs/client.cert”’

p.s conf file is:  
cafile /etc/mosquitto/certs/ssl.ca  
certfile /etc/mosquitto/certs/ssl.cert  
keyfile /etc/mosquitto/certs/ssl.key
