I have HostedZone created by Route53 Registrar, one AWS instance and Elastic Load Balancer. I am able to access my application using load balancer DNS name but not with the domain name. I have created Traffic Policy using my load balancer name (I have simply chosen it from the dropdown list).Once completed I can see it in my Hosted Zone record set as an A traffic policy record.
What I am doing wrong that it does not work? All needed ports are open. I read and read answers from similar question but can't get it work for me..

I have set ALB with fargate, currently I can access to ALB with dns name like this
myapp-LoadB-FDEWFSOAQXD4-f18c75dd4249a10d.elb.ap-northeast-1.amazonaws.com
However it is said this DNS could be changed.
So I want to give this the Elastic IP
I have experienced connection EC2 and Elastic IP.
In Elasitc IP panel I can choose instance.
However, there is not ALB is listed.
How can I set Elastic IP to ALB ? or am I wrong basically?
Two options here, depending on what kind of direction you are heading:
If you do not like the default DNS name
You can create a DNS record that will point to your load balancer. This means that people would be able to surf to your website by using www.whitebear.com instead of myapp-LoadB-FDEWFSOAQXD4-f18c75dd4249a10d.elb.ap-northeast-1.amazonaws.com
See: Routing traffic to an ELB load balancer - Amazon Route 53
If you really want to attach an ElasticIp to a loadbalancer
There are some use cases where it is really needed to be able to surf to a loadbalancer using a fixed IP. You can achieve this by setting up a Global Accelerator on AWS.
With Global Accelerator, you are provided two global static public IPs that act as a fixed entry point to your application, improving availability.
More information can be found on the AWS Global Accelerator page
If you wish to create a 'friendly' name for an Application Load Balancer, you can create a CNAME record in your Domain and point it to the DNS Name of the Load Balancer.
If you wish to point the Apex of your domain (eg example.com), you can use an Alias in Amazon Route 53 to point to the Application Load Balancer. (It is not normally possible to point a Domain apex to a CNAME record, so the Alias capability of Route 53 will do it for you.)

I have an internal load-balancer in aws and I am able to access it successfully from my office network.
I want to put this behind a generic dns so using Route 53, I created a private hosted zone "domain.com"
and then created A record "project.domain.com" pointing to the lb dns mentioned below:
DNS of internal load balancer -> internal-lb-99999999999999.us-east-1.elb.amazonaws.com/
But now from my office network I tried to access "project.domain.com" and it did not work. AM I missing something?
For the setup i have used in the past we do not have the http:// part in the value of the A record in DNS just the load balancer DNS.
Also have you validated that your VPC has DNS resolution enabled?
So there is my load balancer with allocated dns name and group policy - the question how my customer could link it with his hosted zone's record?
and how I could open inbound connection for that domain name?
For now as a workaround I've created hosted zone record in my acc linked to this load balancer ... and created hosted zone record in his route53 to ip (which atm points to my record) ... BUT I think it doesn't actually point to load balancer, but only to it's node ... and I have this problem since obviously ssl certs don't match
NET::ERR_CERT_COMMON_NAME_INVALID
Could somebody point to right solution of this problem ... ?
Your customer provisions a Route 53 Alias record in the normal way, but instead of selecting the balancer from the list of targets (since it isn't shown), your customer will need to paste the DNS Name of the balancer in the box.
If you used different accounts to create your Route 53 hosted zone and your load balancer – Enter the value that you got in the procedure Getting the DNS Name for an ELB Load Balancer.

I have just set up my first "Application Load Balancer" and I chose the SSL option to connect allowing AWS to generate the certificate for me based on my domain (www.example.com).
I have set the target to my EC2 instance and now I want to connect to the Load Balancer but not sure how. If I just connect to the DNS name of the load balancer I get an invalid certificate error.
I have read that I need to set a record for my domain but because the IP of an application load balancer may change, not sure if that is a good idea.
The documentation mentions the following:
Clients can use the Server Name Identification (SNI) protocol
extension to specify the hostname they are trying to reach.
But I couldn't figure out how to do that. I'm very new to Load Balancers and not quite sure how to proceed.
The following problem is easy to solve with AWS Route 53:
Create a hosted zone in Route 53
Choose the name of the hosted zone that has the domain name that you want to use to route traffic to your load balancer
Choose Create Record Set.
Specify the following values:
Name:
Type the domain name that you want to use to route traffic to your ELB load balancer. The default value is the name of the hosted zone.
For example, if the name of the hosted zone is example.com and you want to use acme.example.com to route traffic to your load balancer, type acme.
Type:
Choose A – IPv4 address.
Alias:
Choose Yes.
Alias Target
Find the applicable category in the list (ELB Application Load Balancers, ELB Classic Load Balancers, or ELB Network Load Balancers), and then choose the name that you assigned to the load balancer when you created it.
Routing Policy:
Accept the default value of Simple.
Evaluate Target Health:
If you want Route 53 to route traffic based on the health of your resources, choose Yes
Choose Create.
Also If you don't want to use Route 53 and if it's not at the apex, you use a CNAME to the ELB.
Refer to this Guide
Something like :
my.web.thingy.org CNAME my-loadbalancer-1234567890.us-west-2.elb.amazonaws.com.
And yes you are correct the IP of ELB Changes Frequently and thus it is not recommended to use A Record in DNS.
Hope this Helps
Right now I have two domains registered in Route 53: exampleABC.com and ex.com.
exampleABC.com routes to an Elastic IP connected to an EC2 instance. Works.
I want ex.com to route to the same instance so that a user going to "ex.com" is directed to "exampleABC.com.
I set up an Elastic Load Balancer and Target Group whose registered target is the EC2 instance for exampleABC.com (the target group is connected to the ELB).
I created an A record Alias in "ex.com" Hosted Zone that targets the ELB.
Not sure what to do after this. My thought is that ex.com should now route to exampleABC.com, but the site loads forever without going anywhere.
Please assist
Figured it out! Had to create an S3 bucket for "ex.com" and redirect traffic to "exampleABC.com" then add an A-record alias in "ex.com" that pointed to the S3 bucket.
