Azure Application Gateway
An Azure service that provides a platform-managed, scalable, and highly available application delivery controller as a service.
This is resolved.
My Azure Application Gateway is updated with a new PFX certificate file, but the ingress does not show the TLS, even if I specify the same name

Here is my issue:
I am having my private AKS cluster behind the Azure application gateway as ingress. I got a new certificate today, and I uploaded the certificate in the gateway, and associated with the listener exposing the port 443 to use that certificate. I also updated my ingress with that certificate name and applied. However, I still see the old certificate when I browse the URL. Am I missing something?
