Hi Great community,
I had installed Letsencrypt in dev, test environments. It is working great since everything is running in a single instance. But yesterday, when we had to do for production, we faced a problem with Letsencrypt, since we have AWS Elastic Load balancer. We’re running 2 EC2 instances of our server which is behind the Load balancer.
The problem is when we’re doing ACME Authentication challenge-response, the resource generated on one server is not available on another server(or instance), so it’s failing. How can we mitigate this ?
How to generate Certificates for AWS Elastic load balancer. How to keep it in sync ?
