No songs are showing and web interface is "disconnected"

## Problem description

Airsonic web interface shows albums fine, but the albums don't contain any songs.
I believe the reason is that it is "disconnected" (icon on top right)

### Steps to reproduce

- raspberry Pi 4 running up-to-date raspbian buster
- start with an empty directory /etc/airsonic
- download 11.0.0-SNAPSHOT.20211019030336/airsonic.war
- chown directory and war to airsonic:airsonic
- run airsonic: sudo -u airsonic java -jar airsonic.war

## System information

* **Airsonic version**: 11.0.0-SNAPSHOT.20211019030336
* **Operating system**: raspbian buster
* **Java version**: openjdk 11.0.12 2021-07-20
* **Proxy server**: None
* **Client**: Firefox 93.0

## Additional notes

* I have started airsonic around a dozen times, and it was actually working and "connected" twice (without changing anything)
* I remember having the same problem six month ago, and just giving up (going back to the previous version)
* This is the stacktrace it prints when I click the "disconnected" icon:
