 > Note: do not attempt to use `https://127.0.0.1`. Use `localhost` and accept the self-signed certificate. Caddy has an automatic TLS handling that auto-trusts some local-based hostnames like `localhost`, but it does not apply to IP addresses. More details [on Caddy's "automatic https" docs](https://caddyserver.com/docs/automatic-https#hostname-requirements).
