I have a domain called
abc.xyz.com for which I have installed
letsencrypt on that (apache for web serving) Ubuntu 16.04 as OS and added
A record set in
Route53 for some time - a year. Now the same thing AWS has launched called as
AWS Certificate Manager.
I have created a wildcard certificate as
*.xyz.com in AWS Certificate
Manager and created a CNAME entry
abc.xyz.com in AWS Route53 and using
*.xyz.com as my certificate name in the Elastic Load Balancer with 2 instances.
The Problem is the request is routing back to old instance
(A record) with the letsencrypt certificate. We have also checked with many tools like
dnschecker.org as well
dig/nslookup command but found no look.
Please help us out.
