Proxy Node Connectivity Check

Proxy Node Connectivity Check

Batch-check proxy node TCP reachability, connect latency, and TLS handshake status to quickly identify reachable endpoints.

Server-side checkTCP + TLSOne by oneWaiting

What it can answer

Useful for filtering nodes with closed ports, timeouts, refused connections, or obvious TLS issues.

It is not a real speed test

The value shown here is server-to-target TCP connect time, not proxy download speed.

It does not prove final usability

It does not fully validate vmess, vless, trojan, or ss auth, transport parameters, or outbound access.
