I have an elastic load balancer in an AWS VPC.
I can access the resources successfully behind the load balancer exposed on different ports - standard https 443 and a couple of higher ones say 8888.
all work - I get the expected security warning but can ignore and access the service.
I then added a CNAME record for mysite.example.com to point at https://aws-elb.xxxxxxxxxxxx.region.com and got a cert for mysite.example.com.
Now I can access
I was under the impression that the CNAME would just route through to the underlying url and all would work?
