I certified my domain using AWS Certificate Mangager which requires to add a CNAME to my current domain. So far so good, verfication worked.
Now I set up a load balancer. As the public IP can change over time, it's not advised to set an A record to my domain. AWS tells me to add another CNAME record that points to the endpoint of my load balancer. This is not possible as I am not able to set two CNAME records.
Does anyone know a workaround?
Ok it's late. I AM able to set two CNAME records. Sorry for the confusion.
