In addition to above, you may follow what I had to do to fix the problem.

Troubleshooting of In use – No

1. I had to create an Application Load Balancer

2. Redirect traffic from port 80 to port 443

3. Associate the Certificate with port 443

4. Create an A record with the ALB instead of the ip address

5. I had to create CAA record.
