CodePudding user response：

You can't re-use the same certificate on your ALB which you used on cloudfront. If you want SSL on ALB, you need to setup new domain for it, e.g. alb.example.com, get SSL cert for that new domain, and deploy it on ALB:

Client --- (HTTPS example.com) ---> CF (SSL for example.com) ---- (HTTPS alb.example.com) ----> ALB (SSL for alb.example.com)
