Unable to connect to Load balancer on port 443

I have a Load balancer listening on port 443. I am unable to telnet to the DNS name on port 443 from either the EC2 or my own IP at home. The LB allows inbound connections from ALL IPV4 and IPV6 and allows for LB to EC2 host connectivity outbound to my EC2 instance (172.31.39.228) The health check on my EC2 listener targets is also failing. I am assuming that this is due to the VPC configuration. I am NOT a networking expert as someone set up the VOC for me. Any help is greatly appreciated thx Charlie DIDonato

I have a VPC with Network info below public subnet-925291ea Available vpc-5d3e4f25 | public sphof 172.31.16.0/20 – 4086 us-west-2a usw2-az1 us-west-2 – acl-32d41d49 Yes Yes No - No 064138676421 – subnet-a3cb27e9 Available vpc-5d3e4f25 | public sphof 172.31.32.0/20 – 4088 us-west-2b usw2-az2 us-west-2 – acl-32d41d49 Yes Yes No - No 064138676421 – subnet-946a3fbf Available vpc-5d3e4f25 | public sphof 172.31.48.0/20 – 4091 us-west-2d usw2-az4 us-west-2 – acl-32d41d49 Yes Yes No - No 064138676421 – subnet-e0b964bd Available vpc-5d3e4f25 | public sphof 172.31.0.0/20 – 4088
