iOS App shows router login screen instead of Home Assistant interface

[MrDadoo]

iOS device model, version and app version

Model Name: iPhone 15
Software Version: 26.1
App version: 2025.10.0

Home Assistant Core Version

25.10.4 and I've seen it on previoius versions.

Describe the bug
Sometimes when starting the app, my routers web login screen is shown. Refreshing the app by swiping down just refreshes the screen. By force quitting the app and restarting it shows my Home Assistant as normal.

To Reproduce
I have not round a reproduction strategy. So far it happens randomly.

Expected behavior
Refreshing by swiping down should give a fresh connection, not jusat update of existing - eventually incorrect - connection.

What is the URL that you are using?

Internal URL: htp://192.168.112.31:8123
External URL: http://www.myowndomainname.eu/

No clue why this could be happening, did it ever happens on a normal browser? It looks like something in your networking setup.

Perhaps it tries to resolve the DNS of your remote domain as internal and then faces your router

[MrDadoo]

On internal network it has an IP and therefore no name to look up in DNS. But it might be the problem after all if the phone does not realy know if its on WiFi or cell network…. I’ll give my network a configuration change and see of it is because of that. /Per8 nov. 2025 kl. 12:08 skrev Bruno Pantaleão Gonçalves ***@***.***>:bgoncal left a comment (home-assistant/iOS#3941) No clue why this could be happening, did it ever happens on a normal browser?

You can confirm the theory by removing your local IP from the app

[MrDadoo]

I removed some local static DNS names on my network without success.  I also ensured that VPN were disabled. I have not removed my local IP from app as the app will not work when I sm on my home network. Problem still occurs /Per8 nov. 2025 kl. 12:50 skrev Bruno Pantaleão Gonçalves ***@***.***>:bgoncal left a comment (home-assistant/iOS#3941) You can confirm the theory by removing your local IP from the app —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>

Closing since this is related to network configuration and not App functionality issue.
