Port name is not under naming convention. Protocol detection is applied to the port.
Authentication policy with JWT targets Service with invalid port specification.
A namespace has more than one type of injection labels
An Istio annotation that is not valid
A service registry in Mesh Networks is unknown
There aren't workloads matching the resource labels
No caCertificates are set in DestinationRule, this results in no verification of presented server certificate.
No caCertificates are set in DestinationRule, this results in no verification of presented server certificate for traffic to a given port.
A VirtualService rule will never be used because a previous rule uses the same match.
A VirtualService rule match duplicates a match in a previous rule.
Host defined in VirtualService not found in Gateway.
The resource has a schema validation warning.
Virtual IP addresses are required for ports serving TCP (or unset) protocol
A resource is using a deprecated Istio annotation.
An Istio annotation may not be suitable for production.
Two services selecting the same workload with the same targetPort MUST refer to the same port.
Duplicate certificate in multiple gateways may cause 404s if clients re-use HTTP2 connections.

Virtual service using JWT claim based routing without request authentication.
Proxy may prevent tcp named ports and unmatched traffic for ports serving TCP protocol from being forwarded correctly for ExternalName services.
This EnvoyFilter does not have a priority and has a relative patch operation set which can cause the EnvoyFilter not to be applied. Using the INSERT_FIRST or ADD option or setting the priority may help in ensuring the EnvoyFilter is applied correctly.
The REPLACE operation is only valid for HTTP_FILTER and NETWORK_FILTER.
The ADD operation will be ignored when applyTo is set to ROUTE_CONFIGURATION, or HTTP_ROUTE.
The REMOVE operation will be ignored when applyTo is set to ROUTE_CONFIGURATION, or HTTP_ROUTE.
This EnvoyFilter does not have a priority and has a relative patch operation (NSTERT_BEFORE/AFTER, REPLACE, MERGE, DELETE) and proxyVersion set which can cause the EnvoyFilter not to be applied during an upgrade. Using the INSERT_FIRST or ADD option or setting the priority may help in ensuring the EnvoyFilter is applied correctly.
The Gateway API CRD version is not supported
The Telemetry with empty providers will be ignored
The Istio proxy image of the pods running in the namespace do not match the image defined in the injection configuration.
A Telemetry resource selects the same workloads as another Telemetry resource
More than one telemetry resource in a namespace has no workload selector
The credential provided for the Gateway resource is invalid
