Getting net::ERR_CERT_COMMON_NAME_INVALID when accessing AWS ALB

Security
#1

I am trying to access my AWS Application Load Balancer(ALB) but I am getting a net::ERR_CERT_COMMON_NAME_INVALID instead.

Current Scenario:

  • ALB has an HTTPS:443 listener (only one listener is present) with an SSL Certificate provided for my domain example.com & *.example.com (which is Cloudflare hosted).

I would be more than happy to provide any further details required to support my query.

Thanks in advance.

It sounds like that hostname is not proxied by Cloudflare.
