HTTPS_UNAVAILABLEThe site could not be loaded over HTTPS.
The request to https://<domain>/ or a redirect after it failed. The reason in the evidence says where: no address, an address that is not public, a refused connection, a certificate problem (tls), a timeout, a response that broke the HTTP rules, or a redirect to a URL the check will not follow.
Recommendation: Serve the site over HTTPS on port 443 with a valid certificate, and keep redirects on http or https URLs with public host names.
