A user connected to Prisma Access reports that traffic intermittently is denied after matching a...

The reported symptom — traffic intermittently falling through to the bottom Catch-All Deny rule, bypassing the HIP-based policy that should be matching first, and being resolved simply by refreshing the VPN connection — is a classic signature of stale or lost user-to-IP mapping combined with expired HIP state, rather than a fundamental policy configuration error, which is why refreshing the session (forcing re-authentication and a fresh HIP report) restores correct behavior. If user mapping for the connected session is being learned or refreshed from a source other than the gateway ' s own authentication event (for example, User-ID redistribution or another mapping source with different timing or reliability characteristics than the gateway ' s native session state), that mapping can become inconsistent with the live GlobalProtect session, causing the HIP-enforced rule ' s user-based match criteria to intermittently fail — this is option B. Separately, the firewall periodically expects HIP report checks from the connected endpoint to keep its HIP-based match state current; if a report check is missed due to a client-side timing issue or transient connectivity blip, the firewall can lose the HIP match state for that session even though the tunnel itself remains up, causing subsequent traffic to fail HIP-based rule matching and fall through to the deny-all rule — this is option C. " Collect HIP data " not being enabled (option A) would cause a total, consistent failure to match HIP-based policy from the outset, not the intermittent pattern described. A time-of-day schedule on the HIP rule (option D) would produce a predictable, not intermittent and refresh-resolved, pattern of denial.
