I enabled remote debugging of webview in the app but I don't get any error log in my home assistant instance

This is the log I download from the app

I installed a VM in Proxmox with Home Assistant OS and the problem remains the same, if I access it from any web browser it opens perfectly but if I do it from the Android application it does not load, the Home Assistant logo continues loading indefinitely.

just to confirm using chrome for android on the same device works as expected?

[JulioVillamizar]

Yes, I also entered through Chrome for Android and it loaded fine.

I'm guessing this has something to do with authentication? The app works differently than a browser for that and the iframe probably cannot access it. At the same time that also makes it tricky to fix. No obvious errors or blocked requests when using remote debugging. We may need someone from the frontend team here...
