Is your HTTPS certificate still valid?

Certificates expire, DNS can point the wrong way, and some pages still load scripts over plain HTTP.

When you ship a vibe-coded app, your host usually turns on HTTPS for you. But certificates expire, DNS can point the wrong way, and some pages still load scripts over plain HTTP.

How to check:

  1. Open your live URL in Chrome.
  2. Click the lock icon next to the address.
  3. Confirm it says the connection is secure and note the certificate end date.
  4. If Chrome says "Not secure," fix DNS and SSL on your host before you share the link.

Also open DevTools, go to the Console, and look for mixed-content warnings. Those mean an HTTPS page is still pulling something over HTTP.
