ECS with ALB and SSL certificate issue: net::ERR_CERT_COMMON_NAME_INVALID

I have an aws ECS setup and using ALB for the load balancer. The container task is running on port 8080. I have also added an HTTPS listener with SSL Certificate from ACM, which forwards the requests to the container.



Now I have one issue here. When using curl or postman to contact the load balancer's DNS name, I get the response from the app perfectly. But when using the very same DNS name in my frontend and running in frontend app locally (localhost:3000), and the request is generated from Chrome I get the following error:
net::ERR_CERT_COMMON_NAME_INVALID



How can I resolve this issue?



I also tried deploying the app to my test env, so instead of localhost, I have https://example.com which now matches the Domain name of the Certificate (*.example.com). But still same results.

  • I get this now: curl: (35) schannel: SNI or certificate check failed: SEC_E_WRONG_PRINCIPAL (0x80090322) - The target principal name is incorrect.
