I have a domain registered with dynadot. It is being hosted with Amazon Web Services (AWS).
I have a problem. Visitors can't see my site when they type: www. in front of the domain on their on their web browsers (Safari, Firefox, Chrome, etc) . The message you get is a: Server Not Found page.
However, they can see my site when they simply type my domain without the www. in front of it.
Also important to note. I am hosting through Amazon Web Services and I've got someone else handling my AWS account because it's way too technical for me.
dynadot support gave me a link to the solution of my problem here: https://www.dynadot.com/community/help/question/create-A-record
I will wait a min. of 20 minutes to a max of 24 hours to see my results. If I don't return to comment, you can assume the problem was via the instructions found on the link above.
