Hi, I’m trying to make my HA instance available from outside of my network. Following multiple guides, my current configuration looks like the following:
System: Home Assistant OS (14.1), running Home Assistant 2025.1.2
Installed (relevant) add-ons: Duck DNS, NGINX Home Assistant SSL proxy
Duck DNS config:
domains:
- <subdomain>.duckdns.org
token: <token>
aliases: []
lets_encrypt:
accept_terms: true
algo: secp384r1
certfile: fullchain.pem
keyfile: privkey.pem
seconds: 300
NGINX config:
domain: <subdomain>.duckdns.org
hsts: max-age=31536000; includeSubDomains
certfile: fullchain.pem
keyfile: privkey.pem
cloudflare: false
customize:
active: false
default: nginx_proxy_default*.conf
servers: nginx_proxy/*.conf
real_ip_from: []
Exposed port: 443
configuration.yaml:
[...]
http:
use_x_forwarded_for: true
trusted_proxies:
- 172.30.33.0/24
Port forwarding on router:
From what I understood, this should suffice to make my instance accessible. However, accessing https://<subdomain>.duckdns.org only yields (after a long time of loading) “This site can’t be reached: <subdomain>.duckdns.org took too long to respond.”
Open Port Check Tool - Test Port Forwarding on Your Router shows that port 443 is open. Can anyone explain to me what I’m doing wrong?
