mopidy service - Network is unreachable

[tmgnpp]

Hi, everytime I started my freshly installed Box (master, Release 2.8.0) I need to restart the mopidy service to get spotify tracks playing.

I've checked the journalctl -u mopidy and found the following:

Feb 28 20:46:32 phoniebox mopidy[631]: DEBUG    [SpotifyBackend-7] mopidy_spotify.web Fetching https://auth.mopidy.com/spotify/token failed: HTTPSConnectionPool(host='auth.mopidy.com', port=443): Max retries exceeded with url: /spotify/token (Caused by NewConnectionError('<urllib3.connection.HTTPSCectionPool(host='auth.mopidy.com', port=443): Max retries exceeded with url: /spotify/token (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0xf3914e50>: Failed to establish a new connection: [Errno 101] Network is unreachable'))

I suggest this means there are issues while waiting for the networking and this explains why it does work if I restart the service.
The service config was declared this way (no adjustments from me):

pi@phoniebox:~ $ vim /lib/systemd/system/mopidy.service
[Unit]
Description=Mopidy music server
After=avahi-daemon.service
After=dbus.service
After=network-online.target
Wants=network-online.target

After=sound.target

[Service]
User=mopidy
PermissionsStartOnly=true
ExecStartPre=/bin/mkdir -p /var/cache/mopidy
ExecStartPre=/bin/chown mopidy:audio /var/cache/mopidy
ExecStart=/usr/bin/mopidy --config /usr/share/mopidy/conf.d:/etc/mopidy/mopidy.conf

[Install]
WantedBy=multi-user.target

I've noticed that the service should wait for the networking to be declared as online.
I'm not that familiar with systemd services. Can anyone give me a hint where to find the problem?

Thanks in advance!
