Application Load Balancer getting 502 bad gateway error with Windows Server 2022

If you’re on the server locally. Does https://127.0.0.1 work?

If not you will need to setup an ssl cert.

If it does you’d need to check the ALB and EC2 security groups to allow https.

Thank you, Gary. I appreciate your help. The service (website) does work locally, and from the outside. It just does not work through the ALB. I have checked and re-checked the security groups numerous times. The same policy that allows http (80) also allows https (443).
I need to make one correction to my original post. The EC2 instance is Windows Server 2022, if that makes a difference.

I have been able to confirm that the ALB is getting a TCP RST from the windows 2022 server for HTTPS requests. I just don't know why. The troubleshooting articles just says, " load balancer can't establish a TCP 3-way handshake with the target".
