Airsonic-advanced web player does not work

I changed from airsonic to airsonic-advanced, I did a clean install not an upgrade. The web player does not work, there is no way to hear the music from the browser, while the android app works or it works from the web if I share the music with a guest, the guest hears the music.

To this problem I add that if I access via SWAG proxy, there are pagination errors, I do not see the tracks and a window appears to start the radio.

Any idea?
