(foo.com.au is my domain name)
server3.foo.com.au is my original Google Cloud Debian hostname FQDN. Virtualmin was installed to this hostname fqdn.
foo.com.au is the new virtualmin virtual server i just created on the above instance
have i made a bad mistake in doing this???
My original virtualmin install system hostname is server3.foo.com.au (internal ip address 10.152.0.4)
I setup my whmcs.foo.com.au virtual server, and have that working. I should mention that i am having problems with the whmcs.foo.com.au Letsencrypt SSL certificate installation, it is still not completely resolved, i have successfully downloaded certificate through virtualmin but i still get browser invalid certificate error...so its still using my self signed one)
I decided to create my parent website for webhosting on a new virtualmin virtual server. So i have created a new virtual server called foo.com.au.
My registrar zone records are as follows
foo.com.au. A 3600 188.8.131.52 Remove / Update
mail A 3600 184.108.40.206 Remove / Update
mail.whmcs A 3600 220.127.116.11 Remove / Update

foo.com.au. NS 3600 ns2.partnerconsole.net. Remove / Update
foo.com.au. NS 3600 ns3.partnerconsole.net. Remove / Update
foo.com.au. TXT 3600 "v=spf1 a mx a:foo.com.au ip4:10.152.0.4 ip4:126.96.36.199 ?all" Remove / Update
whmcs TXT 3600 "v=spf1 a mx a:whmcs.foo.com.au ip4:10.152.0.4 ip4:188.8.131.52 ?all"
As soon as i completed the creation of new virtual server foo.com.au , my access to my original virtualmin/webmin control panel at https://server3.foo.com.au:10000 has completely shit itself. I now see a web browser invalid SSL certificate authority error (so i assume its reverting back to my self signed one on the server?), and the Webmin/Virtualmin dashboard is nothing more than a blank grey screen that appears to be stuck in some kind of loop???
I can see the package updates Bell and can click on it, but that is all (everything else is completely blank). I have root access to dashboard interfaces for my virtual servers (whmcs.foo.com.au and foo.com.au) without any problems i just cannot access server3.foo.com.au dashboard.
What have i done wrong? How do i fix this?
(is this because my original install is a subdomain and i have now added the parent domain as a virtualmin virtual server under this subdomain Webmin Server? (I hope you understand what i mean)
If i delete the new virtual server "foo.com.au" that i just created, will my problem be resolved or is it too late and that would only make things worse?
