# The https address did not answer cleanly

Browsers show a warning page or refuse the connection, so most visitors never reach the app at all.

## Why AI-built apps get this

An AI builder gives you HTTPS on the hosted address and stops there. The moment you point your own domain at it, the redirect, the certificate and every hard-coded http:// in a copied snippet become yours. Nothing in the build warns you, because from the inside everything still works.

## Evidence line

GET http://example.com returned 301 to https://example.com, certificate valid to 2026-12-01

## The fix

Check the certificate on your hosting or domain provider, renew it if it has lapsed, and make sure the domain points at the right host.

## Prompt

The https certificate for this app failed validation. Check it has not expired, that the domain points at the right host, and that the certificate covers this exact hostname. Renew or re-issue it through your hosting or domain provider.
