Route 53 record set not resolving for Elastic Beanstalk instance

Question

I am trying to route a specific subdomain to the url of an Elastic Beanstalk application environment instance. Other routes within that domain are working properly.

My configuration screen for the Route 53 record set looks like this:

I can access the environment using environment.url.elasticbeanstalk.com , but I can't using subdomain.domain.com .

Do you have any clue about what could be going wrong? Maybe something about Elastic Beanstalk Load Balancers or Security Groups?

I found this AWS troubleshooting page. It seems like I am following their configuration properly.

Ok, not sure what happened, but I tried to configure the Record Set again by changing from A-IPv4 address to CNAME with no luck.

Then I changed back to A-IPv4 address and tried to enter again the Alias target to the Elastic Beanstalk environment. When I selected my intended environment environment.url.elasticbeanstalk.com from the list and saved changes, it just worked.

I don't know if it's a bug, but I don't remember changing this value. Furthermore, I could copy the value from the field and test it in a browser with no problem. In any case, I hope this helps.
