What does it mean when the internal ingress resource for AKS Nginx returns a connection timeout?

edit

When the internal ingress resource for AKS Nginx returns a connection timeout, it means that the client was unable to establish a connection with the server within the specified timeout period. This can happen for several reasons, including network connectivity issues, server load, or misconfigured firewall rules. To resolve this issue, you may need to check the network settings, server logs, and firewall rules to ensure that everything is set up correctly.
