Node Connectivity Check

Notes

• Accepts vmess://, vless://, trojan://, and ss:// nodes, plus common Base64 subscription bodies.
• Nodes are parsed with @changfengoss/v2rayse-helper, then sent to the server one by one for TCP connectivity checks and TLS handshake checks.
• The current results are useful for answering:
  • whether the target port is reachable
  • whether server-to-entry TCP connects time out, get refused, or look unstable
  • whether TLS handshake succeeds and whether certificate issuer or expiry looks suspicious
• The current results do not directly answer:
  • the node’s real download speed or final throughput
  • whether it behaves the same from your local network
  • whether vmess / vless / trojan / ss can complete full protocol validation
  • whether ws / grpc / reality / auth / outbound access all work correctly
• Treat it as an entry health-check tool, not a final speed test or final usability validator.
• All checks run server-side; the browser never connects to target nodes directly.
