I was updating the DNS records for this site and it wasn’t working for a while which confused me. I had gone into Route 53 and then updated the name servers by clicking on Hosted Zones and choosing the proper domain names. Following the Wordpress instructions, I then updated the records to use the Wordpress Name Servers.
However, even after waiting over 2 days, I wasn’t able to see the new site. This was a bit confusing as updating the name server should be a very straightforward process.
It took some digging around but then I realised that the domains are registered under the “Registered Domains” section and the name servers there was what needed to be updated. Otherwise, the domain would still be using the Name Servers from AWS.
If the above is not updated, then the domain names would not be directed properly to Wordpress.
