Is there an Internet Gateway attached to the VPC or is it over a NAT Gateway? Can you access Internet from the instance? Here is a detail troubleshooting list.

Two things come to mind here, firstly do you have the security group associated with the new network interface that has the elastic IP atttached? https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/MultipleIP.html#MultipleIPReqs
- You associate security groups with network interfaces, not individual IP addresses. Therefore, each IP address you specify in a network interface is subject to the security group of its network interface.
Second thing is around the software that is listening on port 443, is it set to listen on the IP address associated with the NIC to which the elastic IP is attached? Taking Apache as an example https://httpd.apache.org/docs/2.4/bind.html

Not only is there an IGW on the VPC but is it in the Route Table for the subnet containing the instance as the default route.
Also recommend checking VPC flowlogs for REJECT messages to help troubleshoot.
Hi AWS-User-alantam, Thank you for your reply.
It's route table not associate with IGW.
