I have probably set wrong FQDN while creating ssl certificate.
Now, certificate is installed and site display a ‘Warning: Potential Security Risk Ahead’
I am quite sure it is FQDN as certificate was bought from a company where i have installed ssl successfully in the past.
I get this detail on the site:
-when visiting https: www.mydomain.com: Web sites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for www.mydomain.com. The certificate is only valid for mydomain.com.
-when visiting https mydomain.com:
mydomain.com uses an invalid security certificate. The certificate is not trusted because it is self-signed.
How can I view ssl FQDN and how to fix the issue.
I’ve spent the last number of hours trying to work out what’s causing the error “hostname: Name or service not known” to be produced when I run the command “hostname -f” on the latest version of Debian 9. When I run “hostname” I get the hostname ok though and I suspect that it is something to do with the fact that lightsail automatically alters the FQDN hosts.debian.tmpl file (I think). How to I change the FQDN on a Lightsail instance successfully?

We are currently using sql server hostname and instance name for connecting the SharePoint farm to SQL database instance. e.g: sqlserver1\instance1
Now we are required to use the sql fqdn name instead of host name like sqlserver.domain.com\instance1.
How can we achieve this?
