Solutions

  1. Try another SNI/host
  2. Drop this IP from the pool
  3. Re-scan with the maintenance tooling
Defensive patterns

Strategy: fallback

Prevention

When it happens

Trigger: TLS completes but HTTP check for the host fails (403/incorrect content).

Common situations: IP is CloudFront but the tested distribution/host is not served or blocks direct SNI access.
