The next step (Step 5) will ask for your Fully Qualified Domain Name.
If you purchased your certificate at the namecheap website your FQDN is:
-
example.com (replace with your own domain name, but omit the 'www' part)
otherwise set the FQDN to the domain that you want covered - because you will buy two certificates, one for each:
-
example.com - www.
example.comFinally, if your certificate is covering a different domain altogether like:
secure.example.comthen enter that domain as your FQDN (both in namecheap and godaddy)
