Server online
This host is live, encrypted and ready to serve. Something new is on its way to this address.
The web server is installed, configured and answering requests. Until site content is published, this default page is what visitors see.
Every request is served over TLS 1.2 or 1.3. Traffic between the browser and this host is encrypted in transit.
Requests are multiplexed over a single connection, so pages and their assets arrive with fewer round trips.
The web root is configured and serving. Publish files there and they go live straight away.
How this address is currently set up. Software version numbers are deliberately left off a public page.
Three things take this address from a placeholder to a finished site.
Replace index.html in /var/www/html.
Files are served as soon as they land, and this page is sent with
Cache-Control: no-cache, so there is no cache to
clear.
Create a DNS A record for your domain pointing at
169.58.186.77, then add the domain to the site
configuration so the server answers for that name.
Once DNS resolves, issue a real certificate for the domain. That replaces the self-signed certificate and removes the browser warning for good.
Why your browser showed a warning. This host is reached by IP address, and no certificate authority issues publicly trusted certificates for a bare IP. The connection is genuinely encrypted, but the certificate is self-signed, so browsers cannot vouch for who is on the other end. Attaching a domain name and issuing a certificate for it clears the warning.
