Squeeze with MPD
Looks like on some installations the UPnP plugin has not been enabled.
To enable Squeeze UPnP server go to 3 Dot Menu top right of Squeeze web player, select Server, click the Basic Settings to enable the Drop down menu, scroll to and select Plugins, locate UPnP/DLNA Media Interface (v1.0) tick to include, SAVE Settings
For those Squeeze users who really need Tidal, you can enable Squeeze with MPD and use the mconnectLite App as a solution.
