How to read these results
An independent WebRTC connection collects ICE candidates for each STUN service, then closes. Only public srflx/relay candidates count as UDP egress; mDNS or local candidates are not public leaks.
Failures may be caused by timeout, cross-origin restrictions, browser extensions or upstream limits. Missing results are not treated as healthy or unlocked. Retry failed items, or compare local history after switching networks.
