Can you connect to this internal URL using iOS Safari? Any security warnings it gives you?

[merryflag4173]

Hi! See below for the screenshots of what I get (Mac, iPhone, iPad):    The iPhone looks to be connecting successfully, but the iPad is not. All devices are connected to the same SSID & do not have any VPN on.

I think I am encountering the same issue. The new app isn't respecting the scheme defined when connecting to a server. I specify https://servername when adding the server but:
In nginx access log, I see 301 redirects to HTTPS on the /api/websocket endpoint
In the app I get a Starscream.HTTPUpgradeError
In the exported app logs I see
[Error] [main] [Environment.swift:75] init() > WebSocket: Error: Optional(Starscream.HTTPUpgradeError.notAnUpgrade(301, ["Server": "nginx/1.26.3 (Ubuntu)", "Content-Type": "text/html", "Date": "Mon, 26 May 2025 03:17:41 GMT", "Connection": "keep-alive", "Location": "https://dev-hass.makerland.xyz/api/websocket", "Content-Length": "178"]))
With TCPdump I see traffic going to port 80
04:05:09.417593 eth0 In IP 10.3.5.140.52083 > hass02.makerland.xyz.http: Flags [S], seq 600926463, win 65535, options [mss 1460,nop,wscale 6,nop,nop,TS val 4049053127 ecr 0,sackOK,eol], length 0
In the configuration.yaml, I've defined the URLs with HTTPS also. HTTP isn't mentioned anywhere but starscream is trying to connect via insecure websocket. Not sure if that makes it a bug better suited for the starscream repo. I can't tell if it's a bug in the implementation of the library or the lib itself. Swift is up there with the programming languages that confuse me the most.

Actually now that I think about it, this might not be related. The original poster probably isn't using https. I will open a new issue if nobody tells me otherwise.

My iOS Home Assistant Companion app stopped working today. I can still connect to my HA server (a local Raspberry Pi) via browsers from my laptop, but not from Safari or from the app on my iPhone. Perhaps it is an iOS issue.

iOS version: 18.5
Home Assistant Companion version: 2025.5 (2025.1264)

Safari says: Safari couldn't open the page because the server stopped responding.

When I try to add a server from the app, it cannot find any servers. When I try to add the server URL manually I get:

We couldn't connect to Home Assistant
...
Description: The request timed out.
Domain: HomeAssistant.OnboardingAuthError
Code: 1

I had the same problem after I sent a notification from Home Assistant to my iOS app for the first time. As a result, the Home Assistant app could no longer find the local server. The homekit bridges were also no longer accessible from the Apple home app. Resetting the network connections on the iPhone fixed the problems.

I'm having the same issue. I think my issue is partially related to the fact that I'm using old hardware/OS.

I have a new iPadAir with newest iPadOS and it is working fine there.
However, the following are having problems:
My MacBook Air M1 is on MacOS Monterey v12.7.6.
My iPhone XS Max is on iOS 17.4.1
My iPad Pro 3 is iPadOS 17.7

Now the weird part is that, if I connect my laptop to the internet using internet sharing from my iphone, then I can access the homeAssistant from outside fine, but internally only the new devices connect fine.

On my MacBook Air, I have the app for MacOS. here are the errors I get with it:

Description: 
 
Invalid HTTP response (403) for http://192.168.xxx.xxx:8123/auth/authorize?response_type=code&client_id=https://home-assistant.io/iOS&redirect_uri=homeassistant://auth-callback. 
 
Domain: 
 
HomeAssistant.OnboardingAuthError 
 
Code: 
 
1 

here is also part of the log from the app:

Any chance your IP was banned in HA? Since when you connect through your phones hotstop (IP changes) it succeeds

[Tonguc-Endem]

Yes, my problem apparently was ip_bans.yaml. After going through everything for hours through NginxPM, DNSMasq, SSL, etc and I even installed a new HAOS vm on ProxMox, (current is on Pi4) I finally realized the problem is ip_bans. I removed the entries in it and restarted HA and it worked but the problem is this keeps happening. The great thing is that there is no ip_bans_whitelist.yaml or something like that. I found this ban_allowlist and I will give it a try.

Another thing is that I had to delete site data from chrome.
click icon on address bar, click site-settings, then delete data.
Did it both for ip and https name. Chrome was using expired certificate for some reason.

I hope this helps someone.

I am also unable to connect to HA using the internal URL http://homeassistant.local:8123 or via IP address from an iOS device. I do not have an external URL for access outside of my local network.

2025.7.4

Describe the bug

The iOS app will not connect to my HA server by its IP address or the local URL http://homeassistant.local:8123.

To Reproduce

• Install a fresh copy of the HA iOS app (to ensure no previous servers)
• Click "Enter address manually", the server on the local network is not detected automatically
• Enter the URL http://homeassistant.local:8123 or the IP-address equivalent
• Click the "Connect" button
• Receive error: "A server with the specified hostname could not be found."

Expected behavior

• The app connects and displays the default dashboard.

I do not have an ip_bans file.
