about

nx_net_diag.nx -- IN-PLACE network troubleshooter (operator 2026-07-04: "we need a tracert/ping type capability so the smart fallback can troubleshoot + resolve in place"). Layers the failure so we know WHICH layer breaks instead of guessing: DNS resolve -> TCP connect -> send a BROAD browser-like TLS 1.2 ClientHello and READ exactly what the server returns (ServerHello=answered / Alert=negotiation-refused-with-reason / nothing=silent fingerprint drop). This is what cracked "ukdevilz fails but Waterfox works from the same IP": it distinguishes a network block (never happens -- DNS+TCP fine) from a TLS-fingerprint/cipher issue. usage: nx_net_diag <host> license_tier: ORIGINAL
