What This Tool Checks

The TLS certificate tool opens a bounded TLS handshake and reports subject, issuer, validity dates, days remaining, and alternative names when available.

When To Use It

Use it when users see certificate warnings, after renewing a certificate, or before switching a hub to NMDCS or ADCS.

Why It Helps Hub Owners

Secure Direct Connect endpoints need reachable TLS and a certificate that matches the hostname clients use.

What To Check

  • Expired certificates can make secure clients refuse the hub.
  • Name mismatch often happens when a certificate does not include the hub hostname.
  • Some hubs use custom certificates; review client expectations before changing TLS settings.

Hub TLS Certificate Tool

Inspect the certificate returned by a public TLS-enabled hub or web endpoint.

Enter a public hostname, IP address, or hub-style address such as dchub://example.com:411.
Enter a TCP port from 1 to 65535.
