[BUG] emulator sometimes not loading on ios

[Bascht74]

Make sure you're on the latest stable or beta build

• [x] I have tested this on the latest stable or beta release

Is this a bug in companion itself or a module?

• [x] I believe this to be a bug in companion and not a specific module

Is there an existing issue for this?

• [x] I have searched the existing issues

Describe the bug

I use Safari on iOS 26. The URL I entered is: http://192.168.249.1:8000/emulator/main

When I enter the URL, Companion sometimes fails to load the page. Clearing the cache allows it to function again for a while.

Since Safari allows you to add websites to your home screen as web apps, it would be beneficial if this feature worked properly.

If the error occurs in a web app, the web app must be deleted and reinitialized for it to function again. Clearing the cache is not sufficient in this case.

Steps To Reproduce

1. Open emulator page(iPhone)
2. Change some stuff
3. Page ist not shown anymorge. Even closing / opening the browser doesn't help
4. Remove the cache on employers

Expected Behavior

The page is opened. With Chrome it is working

Environment (please complete the following information)

- OS: IOS 26.1
- Browser: Safari
- Companion Version: lastest stable and latest beta, both show this behaivior with safari.

Additional context

Maybe this is the same as what I have been seeing during development, of the websocket sometimes taking a weirdly long time before it gets opened (or attempts to be opened by the looks of the debug logs).
I assumed it was a development/ipv6 thing, but perhaps not

https://github.com/user-attachments/assets/4b65e3b4-7710-4c8d-96c0-107b1caf5b48 I'm also having this bug since updating to the most recent build from 3.5.5. But it's not limited to iOS Safari, it appears to be a Safari-specific problem on macOS as well. Chrome on iOS and MacOS work fine. Might be a webkit/Safari-specific issue.

I am also having this problem regularly in the last month either from iOS updates or Companion updates. Everything was working fine before. Now it takes a long time to load emulators.

I have encountered this issue as well. When trying to open companion from a home screen bookmark it loads for a while and eventually gives me a “WebSocket Closed” error.

I have had the emulator added to the home screen through Safari for a few years now and haven’t had any issues until now. I am able to go to the emulator if I type it into a webpage directly, but I cannot access it from my home screen bookmark. I can’t say for sure, but if I had to guess, I believe it would’ve been updating to the new iOS 26. Because I haven’t updated my companion until just now (4.1.0—>4.2.1) to try and resolve this issue.

One thing that I find interesting is that some people above can’t access it at all, where I only can’t access it from my home screen bookmark. This goes for both my iPad and my iPhone. If I were to type it in directly or to open the emulator from the main dashboard, no matter what browser, I don’t have any issues.
