JSon.Parse error starting moode

[dad33]

Hello,

now i have tested multiple variants of installing the actual 8.3.6(64bit) moode audio on my raspberry pi 4 (4GB). I used the raspberr pi imager and
the pre- configuration of a moode user.

After writing the image and starting the first time, moodeaudio wants to have an

 "acces point" password also. Setting this password and configured my wlan i restarted the pi.

I tooks a long time...i connect over the lan port...firefox browser tells me:

MPD error...JSON.parse unexpected end of date at line 1 column 1 of the JSON data

endless loop with this information...after about 3 minutes, Moodeaudio starts

Whats going wrong?

Thank you.
