STATUS_FWP_NEVER_MATCH
The enumeration or subscription filter can never match anything
WFP enumeration and notification APIs can restrict results by template. This status tells you the template is contradictory or targets an impossible combination, so waiting for matches will not help.
Inspect the filter conditions against the layer fields available at that point. A condition that can never be satisfied often indicates the wrong layer, field type, or policy-generation assumption.
What to inspect
- Review every template condition for mutually exclusive values.
- Check layer, provider, sublayer, and object type together.
- Simplify the template until objects are returned, then add conditions back.
