Hi everyone,
I’m having an issue with the Home Assistant Companion app on my iPhone and Mac. The app only reliably connects when I’m on Wi-Fi. Not only does it work on my home Wi-Fi, but it also connects without issues on other Wi-Fi networks. When I use my Orange Spain mobile data, it usually doesn’t connect—sometimes it works, but most of the time it keeps loading and never connects. This also affects Home Assistant features that rely on mobile location tracking.
My partner, who uses Movistar, has no issues. Interestingly, if I access Home Assistant via Safari using my external URL (https://example.duckdns.org:8125), it works perfectly over mobile data.
App settings:
- Internal URL:
http://homeassistant.local:8123 - External URL:
https://example.duckdns.org:8125
Setup details:
- Home Assistant Green running Home Assistant OS
- Core: 2025.12.2
- Supervisor: 2025.12.2
- Frontend: 20251203.2
- Companion app version: 2025.12.2 (2025.1546)
- I’m using DuckDNS (
example.duckdns.org) and Let’s Encrypt (example.duckdns.org/ Port 80) with NGINX (example.duckdns.org/ HTTPS (SSL) Port 8125)
Network configuration:
-
Router: Orange
-
Port forwarding:
- Internal 8125 → External 443 (TCP)
- Internal 8125 → External 8125 (TCP)
I’ve tried reinstalling the app and restarting it, but the problem persists.
Has anyone experienced this before? Could it be something specific to the Orange network or my app configuration? Any suggestions to fix it would be greatly appreciated.
