ERR_NAME_NOT_RESOLVED Route 53 / Elastic Beanstalk - amazon-web-services

I have been trying to connect my domain with my elastic beanstalk instance.
My domain was purchased off GoDaddy and I have updated the nameservers to point to AWS and verified through dig. If dig comes up with the NS, it means GoDaddy is properly configured to point to the DNS right?
The Test Record Set function also does not show any error and has a proper response returned which has NOERROR
Problem is I still receive an ERR_NAME_NOT_RESOLVED everytime I try to load the website on browsers even tried on different devices
I have also checked the alias used in my Hosted Zone and its up and running
What I have already done:
Initialized and created Beanstalk environment - Up and Running
Public Hosted Zone - Created A record for www.mysite.com
GoDaddy DNS NS - updated with AWS 4 nameservers
Checks I have done:
Internal Test Record for A www.mysite.com
Dig Command
What could I be missing?
UPDATE***
So I figured "www.mysite.com' was working but 'mysite.com' alone was not. I'm assuming route53 will automatically use the www A record? But seems like its not?
Hope ya'll could help
Thanks!

Got it to work.
Looks like besides creating a www A record, I had to create a record for the root domain i.e mysite.com in the Record Set of my Hosted Zone
Solved!

Namecheap Domain not working on AWS EC2 Instance

I am new to AWS and facing this issue for the past few days. So any help will be appreciated :)
I have created an AWS EC2 instance and deployed backend&frontend services on SINGLE INSTANCE that are used in my project.
Backend->Java,Apache tomcat,RDS,Elasti cache
Frontend-> Node
And now created a hosted zone under Route53 to host my Namecheap domain in AWS EC2.
Have checked all configs thrice, and added A type(Value as ec2 IP) and CNAME(Value as domain name e.g. xxyyzz.liv) type variables in the hosted zone including modifying nameservers from hosted zone to the Namecheap DNS settings.
Even after long waiting(of 48 hrs) my domain is not getting live, tried multiple times but no help.
This will be caused by misconfiguration. Perform the following steps to rectify this issue:
Ensure you have not replaced the NS or SOA records in Route 53, these should stay as the values that Route 53 generates. If you have replaced their values, create a new public hosted zone and migrate the records to this (excluding NS or SOA).
Run DIG against your domain for the MX record, either by running DIG NS example.com or by using an online tool such as https://toolbox.googleapps.com/apps/dig/. If you get no results back (returning a SERVFAIL) or incorrect name servers back then you will need to update the name server configuration.
Within your public hosted zone in Route 53 look for the NS record, copy the values (there will be 4 nameservers). Then within namecheap follow these instructions for "Custom DNS". Add each name server from Route 53.
By now running DIG again you should be able to see the records that should have previously been accessible. Depending on the TTL of the previous NS record you might find it takes a few hours/days for the DNS to migrate across, although you can clear the DNS cache on your local network.

Route53 / Lightsail: www subdomain does not work

I've registered my domain on Route53, deleted the default hosted zone, and set the name servers to the ones provided by Lightsail. I've also set up a hosted zone in Lightsail with two subdomains: # and www. Both are A records that point to the static IP of my Lightsail instance.
The top-level domain works fine, but the www is giving an "IP address not found" error on my browser. What might be going wrong?
Turns out it just takes a while for the DNS to update.
You can use https://www.whatsmydns.net/ to check if DNS is updated.

Lightsail instance works when you hit http://[domain].com, but not www.[domain].com, using Route 53 as DNS

I'm pretty new to DNS and this is the first time trying to connect a domain name to an IP, so I'm not sure what I'm missing here. I tried connecting both the www and non www NS records to the Lightsail name servers but only the non www option seems to be working. When I try to hit www.[domain].com, I get unresolved hostname. I also added an A record in each hosted zone that points directly to the IP and I'm not sure if they actually did anything, but I can only access the site from the IP or from http://[domain].com. I appreciate any help you guys can give me, hoping its something small.
Here is an album containing my hosted zone and each zone's settings
I think you don't need to use two separate hosted zone for www and the apex domain (non-www). You can have a single hosted zone and create resource record set for www and the apex domain using CNAME or Alias records. Since you already have an A-record for example.com, in the same hosted zone you can create a CNAME record for www.example.com and point it to example.com
Regardless, for the domain not found, it could be due to the TTL.
Hope this helps.

Amazon Route 53 Issues

I have a hosted zone in Amazon Route 53 service and a domain name on a registrar.
In the registrar, my DNS configurations are correctly inserted, with the four address provided by AWS when I create the hosted zone.
In the Route 53 control panel, I have the NS and SOA proper configured as it came configured when I created the hosted zone.
I also created a A Redirection : mydomain.com.br -> xxx.xxx.xxx.xxx (elastic IP)
I'm able to reach my EC2 instance with the A Record: If I type mydomain.com.br on browser it works fine.
My problem is that I'm unable to reach the CNAME's that I've created.
I have a CNAME rule: www.mydomain.com.br -> mydomain.com.br/site but when I put www.mydomain.com.br I get a DNS error on my browser.
The strangest thing is that if I consult www.mydomain.com.br on a site like https://www.whatsmydns.net it points to www.mydomain.com.br/site, which is the correct redirect. The DNS resolution aparently works fine, but I can't get it on the browser.
Any help would be nice. Thanks.
ps: I alredy tried to ipconfig/flushdns and clear chrome's cache
Try this:
Delete that CNAME record
Add an A record in Route53
Name the A record 'www' it should automatically make that www.mydomain.com.br.
Check the ALIAS-yes box
Select mydomain.com.br. from the dropdown box (note there is a PERIOD on the end)
Save and Wait about 5 minutes.
A better (and still very cheap) way to do this might be to set up a 301 redirect in an Amazon S3 bucket. Here is a link to Amazon's tutorial:
http://docs.aws.amazon.com/AmazonS3/latest/dev/how-to-page-redirect.html
Do you have a "www" A record which is pointed to your EIP?

route53 naked domain not reaching amazon elastic load balancer

I`m currently using route53 for 2 domains that points to the same website.
Lets assume they are www.example.com and www.example.com.xx, I`ve created 2 hosted zones and maintained the configuration created by default. So, initially I had entries for NS an SOA in each hosted zone.
My EC2 instances are behind Elastic Load Balancer, so my first step was to create aliases for both domains and it naked domains, having the following scenario:
www.example.com
name type value
example.com. NS Generated value
example.com. SOA Generated value
example.com. A ALIAS to my ELB
*.example.com. A ALIAS to my ELB
www.example.com. A ALIAS to my ELB
www.example.com.xx
name type value
example.com.xx. NS Generated value
example.com.xx. SOA Generated value
example.com.xx. A ALIAS to my ELB
*.example.com.xx. A ALIAS to my ELB
www.example.com.xx. A ALIAS to my ELB
Both domains are pointing to the same ELB, where Apache configs to example.com. Then, my Django app subdomain middleware redirects to example.com(301) if request.get_host contains the .com.xx substring.
It is working perfect for both www.example.com and example.com as for www.example.com.xx, my problem is with example.com.br that never reaches my server.
I`ve already tried to make a PTR entry example.com.br -> www.example.com.br, but it was not the solution.
Anyone can point where my DNS config for this naked domain is failing?
Thank you
Firstly lets worry about example.com.br. [www.example.com.br we will take later]
Did you made changes on ur Domain registrar; so as to give DNS servers as that of Amazon ? What is the output you are getting when u do :
nslookup example.com.br
also what is the output for
ping example.com.br
Yesterday night I was able to redirect my naked domain properly, it was a bug in my brazilian provider that was dealing with the registrar. Actually, I just gave them back the control of the DNS table and took it away (returning it to route53).
Anyway, they were being used as a bridge to the registrar since I was migrating. Now I`m dealing directly with registro.br and the problem is gone.
