When to use it
Use automatic HTTPS when the OneView server directly receives public traffic on ports 80 and 443 and the hostname resolves to that server.
Create a DNS A record:
Type: A
Name: oneview
Value: <public IP that routes to the OneView server>
Required network path
Certificate authorities must reach the server from the public internet. If the server is behind a router, forward TCP ports 80 and 443 to its private address. Cloud firewalls and security groups must also allow these ports.
Installer selection
--hostname oneview.customer.example \
--tls-mode automatic
OneView obtains and renews the certificate and redirects HTTP to HTTPS.
Common failure
If certificate setup reports a connection timeout, DNS may be correct while the public ports still do not reach the server. Check router forwarding, host firewall rules, cloud security rules, DNS proxying, and whether another service owns the ports.
