An update for you @StephDotNet @ahaw021 @steampunkjnkies @jsha,
I have had some success that may relate to all or some of our problems.
Thank you @jsha for the guidance, I did indeed find a nginx config file that was creating the reply - nginx.vpscloud.biz.conf_letsencrypt:
location ~ "^/\.well-known/acme-challenge/(.*)$" {
default_type text/plain;
return 200 "$1.ggSx6hy43AXM901bwJ_Dr4mYLANeJZ8AC4Xxg_N3Bgg";
}
From its date it looks to be left from the failed attempt to create new certs with the VestaCP plugin, which was failing with a timeout - as mentioned in:
After removing this config file "nginx.vpscloud.biz.conf_letsencrypt" the command line process now fails with the same CCA timeout, but at least its making progress!
> Failed authorization procedure. vpscloud.biz (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: query timed out looking up CAA for vpscloud.biz

Now all I have to solve is an issue with one of the major DNS providers in Australia!
I hope this will help point others with VestaCP in the right direction, the nginx config chain of files is located in the "conf" directory for your VestaCP user in my case - "/home/admin/conf/web"
Thanks to all and regards,
Mark.
