WebUI shows only blank screen.

[rspierenburg]

So I've installed the Integration along with the Server Add-on. The server seems to be running fine but whenever I click on either the WebUI button or the Music Assistant sidebar button I'm redirected to a blank page.

Home Assistant Core 2024.11.3
Supervisor 2024.11.4

Music Assistant Server 2.3.3
Music Assistant Integration 2024.11.5

Here is the log for the Server Add-on:

The log suggests the server isn’t running fine as it keeps shutting down… but it looks like something has requested it to be shut down? There is a toggle in the configuration for the add on to start in safe mode. Try that and see if it will stay up long enough to get into the UI

[OzGav]

Firefox is a known problem at times. Edge should work but you can also try chrome. Beyond that look at firewall or other network settings that may be interfering. Do you have other add ons that work ok?

[rspierenburg]

Yep, all my other addons work (Docker Wyze Bridge, Frigate, Zigbee2MQTT).
Chrome was the first browser I tried.

[OzGav]

There is likely something in your network or other setup as no one else is reporting this.

[rspierenburg]

Thanks for all the quick replies, yeah I figured it must be network related somehow. Just wasn't sure if there might have been something in the logs that I had missed.
