Run SSL / TLS Certificate Check

NOT TESTED

DI VPN opens one certificate-verified TLS connection to a public website on TCP 443 and inspects the presented certificate. No redirects or active content are loaded.

Your test results will appear here. Nothing runs until you press the button.

Full tests run only after you start them. Public tools need no extension. An optional extension status check may run in Chrome. Results are not saved to your DI VPN account.

What this tool checks

Expired or mismatched TLS certificates can indicate a configuration or security problem.

Certificate chain and hostname verification
Certificate issuer, expiration and TLS protocol
Only public internet targets are accepted

How to run the test

  1. Enter a public hostname such as example.com.
  2. Run the TLS test.
  3. Review the verified status and expiry.
Important limitation

This checks only one resolved public address from the DI VPN server and does not verify all CDN nodes or certificate transparency records.
