A certificate for a domain

1. Add an A record for panel.example.com pointing at the server, and wait until dig +short panel.example.com returns it.

2. Port 80 must reach the server (provider firewall too).

3. At install, choose 1 and give the name. Or later:

w-ui          # → 20 → 1 → the domain

The menu issues it with acme.sh over HTTP-01, installs it under /etc/wui/certs/panel.example.com/, hands it to the panel and restarts. Renewal is automatic.

4. Check:

curl -sI https://panel.example.com:41234/ | head -1
w-ui settings | grep -E 'cert|Access'

The IP address still reaches the same port, only with a certificate warning — for both, see wildcard through Cloudflare or issue for the IP as well.
